Review of this 2.5G Multigigabit to USB C adapter

The main feature of this new USB Type-C or Thunderbolt 3 to Ethernet adapter, is that we have one 2.5G Multigigabit port, therefore, we can obtain a speed of up to 2.5Gbps in the local network, both in download and upload. Nowadays the vast majority of this type of adapters have Gigabit Ethernet speeds, therefore, we can transfer at a speed of approximately 115MB / s, however, with this device we can exceed the actual 230MB / s without any problem, both in download as upload.

This new adapter allows it to be connected to computers with both a USB Type-C port and also Thunderbolt 3, since both connections are compatible, therefore, we can use it both in Windows computers as also in macOS with Thunderbolt 3 connection. This new device, facing the RJ-45 port that it incorporates, has automatic speed detection, to always synchronize at the maximum possible speed of the link, you can synchronize at speeds of 2500Mbps / 1000Mbps / 100Mbps / 10Mbps, therefore, depending on the local network where we connect it, we will have one synchronization speed or another. Another very important feature is that it supports Full Duplex mode in both 2.5G and 1G, since it is a mandatory requirement of the standard, of course, we have MDI / MDI-X to detect crossed network cables and also work without problems.

On the front of the RJ-45 connector we will find two LED indicators To show us the status of the connection, we can see a green LED that will indicate that the synchronization works at 2.5Gbps, and an orange LED that will indicate that the synchronization works at 1Gbps. Another important detail is that does not require any kind of external power adapter, it is powered directly through the USB Type-C or Thunderbolt 3 port, in fact, the power consumption in operation is 250mA maximum, and the power consumption in standby is 60mA. D-Link has incorporated into this adapter a Energy saving system, because mainly this device will be used in battery powered laptops. Other important features of this device is that it supports the 802.1p standards for QoS, 802.1Q for VLANs, 802.1az for energy efficiency, and also the 802.3x protocol, which is flow control.

The connection cable has a length of 16cm, It is not too long, but it is enough so that it does not disturb if we want to connect a network cable in different positions. The D-Link DUB-E250 is really very small, with dimensions of 53 x 21.5 x 15mm, and a weight of only 28.5 grams, therefore, we can transport it in any pocket of the backpack where we have the PC.

Thanks to the use of this adapter, we will be able to transfer data at approximately 240MB / s, compared to the 115MB / s that the Gigabit Ethernet standard allows us. This means that we can transfer the same amount of information in half the time, therefore, if you are a graphic designer, video editor or want to make backup copies to a NAS server (with Multigigabit speeds and connected to a Multigigabit switch) you can squeeze the maximum 2.5G port.

External analysis

This USB Type C adapter (also compatible with Thunderbolt 3) to 2.5G Multigigabit Ethernet network port, comes in a small white and green box. On the front we will find the main characteristics of the equipment, such as that it is compact and portable to always carry it with us, it is up to 2.5 times faster than the popular Gigabit Ethernet standard, and also that it has support for Thunderbolt 3 in addition to USB type C, therefore, we can use it on both PC and MacOS.

On the back of the box we will find the main features in different languages, it indicates that it has 2.5G Ethernet connectivity, automatic speed detection and also LED indicators on the RJ-45 port to show us the status of the link synchronization. On the right side we can see the main specifications that we have already explained in the introduction, such as automatic speed detection, detection of crossed cables, supports Full-Duplex, does not require an additional power adapter, and is compatible with the Gigabit Ethernet standard and with its speed of 1Gbps, in addition to 100 / 10Mbps as well. Finally, we will need to install some drivers that are integrated into the device itself, so we will have to run the installer on our computer and we will have it installed and ready to go. On the left side we can see the minimum requirements of the USB type C to 2.5G Ethernet adapter, and that is that we will need a computer with Windows 7 or higher, or the operating system Mac OS 10.6 or higher, and we will also see the contents of the box.

Regarding the content of the box, we find the following:

  • D-Link DUB-E250
  • Quick install guide
  • Product guarantee.

The quick installation guide will tell us how we should connect this USB Type C adapter to a 2.5G Ethernet port, it will also tell us how we should install the drivers in Windows, which is simply by clicking on the new unit that the adapter itself generates.

The D-Link DUB-E250 adapter is a really small device, with dimensions of 53 x 21.5 x 15mm, and a weight of only 28.5 grams, in addition, the cable measures approximately 16 cm, ideal for connecting comfortably the Ethernet network cable.

View of the 2.5G D-Link DUB-E250 adapter in detail

At one end we will have the USB type C connector (also compatible with Thunderbolt 3), and at the other end we will have the RJ-45 connector with the typical green and orange status LEDs of the equipment that will show us the synchronization speed. If we have a synchronization of 2.5Gbps it will show it in green, if we have a synchronization of 1Gbps or less it will show it in orange.

On the back of the adapter we will have the exact model of the device, the hardware version, the serial number and also the MAC address of the adapter. Being an Ethernet network card, then logically we have a MAC address.

So far we have arrived with our external analysis of the device, as you can see, the most remarkable thing is the 2.5G Multigigabit port that this equipment incorporates, and also that we have compatibility with both USB type C and Thunderbolt 3 ports.

Test laboratory

The first thing we have done is connect this USB type C adapter to a 2.5G network port to an available port on our PC, specifically we have connected it to a rear USB type C 3.2 Gen 2 (at 10Gbps) port that our motherboard has, therefore, we can ensure that there is no type of bottleneck. As soon as we connect the device, we will get a new 1MB unit in “Equipment”. All we have to do is double click on this unit, execute with administrator permissions and in a few seconds we will have the Realtek driver installed to make it work, and this unit will disappear.

D-Link DUB-E250 Installation View on Windows

Once we install the drivers, we will have direct access to the wired network. As you can see, the synchronization speed is 2.5Gbps because we have used a Multigigabit switch. Depending on the switch and cabling, it will sync at the maximum speed of 2.5Gbps or at a lower speed.

D-Link DUB-E250 adapter sync view

Regarding the properties of the network card, it will indicate that the manufacturer is Realtek, and we can also access all the advanced options of the device to activate or deactivate functionalities. The most important thing that we should modify are the Jumbo frames, in our case, we have configured Jumbo Frames to 9K since it is compatible with the switch used.

We will also have the possibility to configure the priority and VLAN, the power consumption and other parameters that we should not touch, unless you know what you are doing. However, it is advisable to modify the Jumbo frame parameter to maximize the network at 2.5Gbps speed.

The speed that we obtain with this USB type C adapter to 2.5G Ethernet network port is the maximum that the interface provides us, as you can see in the following test with iperf 3. We have connected an iperf 3 server in a Multigigabit switch and this adapter as well, and we have achieved a speed of 2.46Gbps with Jumbo Frames at 9016 bytes:

In the case that you use a typical 1500-byte MTU, the maximum speed that you will obtain will be around 2Gbps approximately, we will not be able to squeeze the full potential of this device.

Regarding file transfer over LAN, having a Multigigabit speed, we must take into account several factors:

  • The equipment connected to the LAN must also have Multigigabit speed
  • The switch that joins all the equipment must be Multigigabit
  • SSDs must be used and not hard drives, otherwise, we will have a bottleneck.

The speed achieved in the transfer is 295MB / s, both in download and upload, since the network card is Full-Duplex.

As you have seen, we will achieve more than twice the real speed than if we used a Gigabit Ethernet connection, this is ideal for environments where we make backup copies or are going to transfer a large amount of data.

Strengths

  • Compact and with a very elegant design
  • USB type C connector that today is the most used in laptops and ultrabooks.
  • Compatible with Thunderbolt 3 technology, ideal for Apple Macs
  • 2.5G Multigigabit network port, prepared for the new speeds of local networks.
  • Actual speed achieved by the DUB-E250 is 2.46Gbps, the highest possible and expected speed.
  • Price: outstanding, we can buy this device for about 60 euros.

Weak points

Last conclusions

This new USB Type-C adapter (also compatible with Thunderbolt 3) to 2.5G Multigigabit network port D-Link DUB-E250 is the perfect complement to your laptop or ultrabook. Normally, the latest models on the market do not have a native Ethernet port, because they do not physically fit in the laptop itself due to the thickness of the connector, having a USB to Ethernet adapter is very important to connect via cable to any local wired network. This model is compatible with both computers that have a USB Type-C port as well as Thunderbolt 3, ideal for use with Apple Mac computers that normally have this type of connectivity.

The speed achieved with the 2.5G Multigigabit port is the maximum that we will achieve, as long as we use Jumbo Frames at 9016 bytes, otherwise the maximum speed that we will achieve will be around the real 2Gbps, something completely normal and that we have previously verified in other cards network. Having the new connectivity with the NBASE-T standard is a point very in favor of this equipment, because we will be able to transfer data at more than twice the speed of the typical Gigabit Ethernet interface.

Regarding the price of about 60 euros, it is an expected price considering that Gigabit Ethernet adapters are around 30 euros approximately. For double the price you will have a little more than double the speed, and you will already be prepared for the speed of the LAN networks of the present and the nearest future.

Taking into account the technical characteristics of this USB Type-C adapter (also compatible with Thunderbolt 3) to 2.5G Multigigabit network port, the performance obtained in the tests and the price, RedesZone’s assessment is as follows:

We hope you liked the analysis of this new D-Link DUB-E250, if you have any questions you can put a comment and we will respond delightedly.

Review of this 10Gigabit Ethernet PCI-e card

The Edimax EN-9320TX-E card also supports the NBASE-T standard, this means that depending on the cable and its length, it can synchronize at speeds of 2.5Gbps and 5Gbps. Therefore, you will not only be able to sync at 100Mbps, 1Gbps and 10Gbps, but also at intermediate speeds of 2.5Gbps and 5Gbps.

This network card incorporates auto-negotiation, depending on the cable and the distance will automatically synchronize at one speed or another. Of course, it is compatible with Auto MDI / MDIX, so we will not have to take into account if the network cable used is parallel or crossed, the card will automatically adjust to connect to switches, routers or other PCs directly.

This Edimax EN-9320TX-E card allows Jumbo Frames of up to 9K, this means that if we use Jumbo Frames in our network we will obtain higher speed, since we will have to send fewer packets, and therefore, fewer headers. This new card also supports the 802.1Q VLANs standard, and of course 802.1P for QoS priority queues.

The Edimax EN-9320TX-E is fully compatible with Windows systems, including Windows 10 and Windows Server versions. It is also compatible with Linux systems with kernel 4.x, 3.x and 2.6.x both 32-bit and 64-bit. This card also incorporates compatibility with VMware ESXi 6.0, 5.5 and 5.1, it is also compatible with Microsoft Hyper-V, Linux KVM and VirtualBox.

Main technical characteristics of the Edimax EN-9320TX-E card

  • Support for 100BASE-TX, 1000BASE-T, 2.5GBASE-T, 5GBASE-T standards (Support NBASE-T, 10GBASE-T)
  • 1 RJ-45 port with speed up to 10G.
  • Incorporates support for 802.1Q VLANs and also 802.1P QoS
  • PCI Express 2.0 x4 interface.

In RedesZone we have made a complete video explaining the main characteristics of this 10Gigabit Edimax EN-9320TX-E network card, a device to take into account if you need to update your network to 10Gigabit.

Once we know the main characteristics, we will see its box and also the network card itself.

External analysis

This 10G Edimax EN-9320TX-E network card comes in a small, white box. On the front of the box we find the main specifications of the Edimax EN-9320TX-E, such as that it is 10 Gigabit, and that it incorporates a low-profile bracket for installation in servers.

On the left side of the box of the Edimax EN-9320TX-E network card we find the contents of the box, the main features, such as that it is PCI-Express 2.0 x4 and that it supports 802.1Q VLAN and 802.1p QoS, as well as the system requirements.

On the back of the box we find the main features of the 10G network card in different languages, but without going into too much detail.

This 10G Edimax EN-9320TX-E network card is perfectly protected by a plastic in the box, the contents of the box are as follows:

  • 10 Gigabit Edimax EN-9320TX-E network card
  • Quick installation guide.
  • CD with the quick installation guide, manuals and also the necessary software to start up the card.

This Edimax EN-9320TX-E network card has a gray heatsink on the top, ideal for keeping the temperature of the chipset of this card under control. At the bottom we find all the circuitry of the network card, and also a sticker with the model and the different certifications that the network card has passed.

On the front of the Edimax EN-9320TX-E network card is where we find the RJ-45 connector, right next to it we find a link and link activity LED, we also find an LED that will quickly indicate the speed synchronization of the network card with the switch / router where we connect it.

One of the strengths of the Edimax EN-9320TX-E card is that it incorporates a low-profile bracket, ideal for installing it in servers without having to buy the bracket in question, because it already comes in the box by default.

So far we have come with the external analysis of this 10 Gigabit Edimax EN-9320TX-E network card, now we are going to go to the test laboratory to check its performance.

Test laboratory

The manufacturer Edimax has provided us with two units of this high-performance Edimax EN-9320TX-E network card. We have tested these network cards with a professional 10G Edimax XGS-5008 switch of which you will soon have a complete analysis in RedesZone.

Once we have installed the Edimax EN-9320TX-E network cards in two computers, one with Windows 7 64-bit and the other with Windows 10 Pro x64, we have connected it to the 10G switch with a Cat6 cable. We must remember that Cat6 cables support 10G speeds over short distances, we have not exceeded 1.5 meters of this type of cable.

Tests with the Edimax EN-9320TX-E card

If we go to the center of networks and shared resources, we will see the status of the local area connection, as you can see we have a 10Gbps synchronization, which we already expected. On the Windows 10 computer we also have 10Gbps synchronization. The card configuration is auto-negotiation and we have activated the Jumbo Frames at 9K.

Regarding the configuration options of the card, as you can see we have the possibility of activating the Jumbo Frames, and also modifying the speed thanks to NBASE-T.

The first performance test we have carried out is to perform a transfer between a Samba server hosted on a PC with Windows 7 and a 10G card, plus a NAS server with a 1G card via Samba. All this at the same time.

As you can see, the total throughput is 305MB / s, approximately 2.5Gbps, and it is that both the hardware of our equipment and the hard drives are bottlenecking, the network card is only at 3325% of its capacity. Here’s another test with CrystalDiskMark pointing to the network drive with the 10G computer and card:

If we carry out a test with iperf3 we can verify that we have achieved different speeds if we use different sizes of TCP windows, this is due to the hardware we are using, and we have not been able to achieve the 9-9.5Gbps that we should achieve under normal circumstances. However, you can see how we are able to send data up to 7.66Gbps:

We must bear in mind that with the hardware used we have not been able to squeeze the 10G port, so if you are going to buy this card you must have a fairly powerful computer to be able to squeeze its maximum speed. This network card is aimed at advanced home users and also SMEs, where we need more speed than 1Gbps. To give you an idea, a SATA3 interface where we normally connect SSDs and hard drives has a maximum speed of 6Gbps, and this network card is capable of providing up to 10Gbps of speed, almost double.

In small and medium-sized businesses there is almost always a NAS server or file server with great hardware, to give ultra-fast data delivery to all employees. In this way, you will be able to squeeze the maximum speed of its 10G port on this card.

software

This network card incorporates a CD with the drivers for the different operating systems, although we can always access the manufacturer’s official website where we will find the latest version. We have verified that the Windows 7 Professional SP1 x64 and Windows 10 x64 drivers work perfectly. An interesting detail is that this CD works for both the Edimax EN-9320TX-E and the Edimax EN-9320SFP + models, which have an SFP + fiber connector and not a copper Ethernet one. In both operating systems we have had to install the manufacturer’s own drivers, the operating system has not been able to detect the card and install the necessary drivers by itself.

Once you have seen the main features of this card, and the performance that we have achieved in the tests, we will explain the strengths, weaknesses and conclusions.

Strengths

  • One RJ-45 port with 10G speed and support for NBASE-T (2.5Gbps and 5Gbps).
  • Performance achieved in tests, we have achieved the expected speed for this type of card, although we have not been able to get the most out of it.
  • Includes a low profile bracket to fit low boxes.
  • Ease of installation, simply click into an available PCIe 2.0 x4 port.
  • It is compatible with any operating system even if it does not include the drivers on any CD, such as Windows 7 and Windows 10 (among others).
  • Passive cooling, so the noise is 0
  • Price: excellent, it costs around 110 euros, a real bargain considering the characteristics.

Weak points

  • We will not take advantage of the maximum performance that this card is capable of providing us if we do not have very powerful hardware, but is that a problem? Of course not, therefore we have not found any weak point to highlight.

Last conclusions

This Edimax EN-9320TX-E network card is a top of the line in its field, it not only incorporates 10GbE technology, but is also compatible with NBASE-T technology. Another very important feature, especially for servers, is that it supports 9K Jumbo Frames.

The performance of this card is excellent, in fact, in few cases we will be able to squeeze the maximum 10Gbps of speed from its RJ-45 port. If we are going to transfer data at high speed, surely the bottleneck is found in the data interface of the SSD / hard drives, or else in the server’s own hardware. In fact, it is very likely that you will have to modify kernel parameters to try to maximize the speed that this card allows you.

The price of this card is around 110 euros, an excellent price since we can update our equipment with 10G connectivity and make the most of our local network. Whether you are a home user or a company, this network card for this price is ideal for you, in fact, we did not expect this network card to drop below 200 euros, so this is great news.

If we take into account the characteristics, the possibilities and the performance of this Edimax EN-9320TX-E card and the price, RedesZone’s assessment is as follows:

We hope you liked the analysis, if you have any questions you can put a comment and we will respond delightedly.

Analysis of this USB 3.0 to 5GbE port adapter

Thanks to this QNAP QNA-UC5G1T adapter will allow us connect to the local network via cable at high speed, and is that it incorporates the NBASE-T standard. Specifically, this USB 3.0 to 5GbE port adapter allows the following speeds:

  • 5Gbps
  • 2.5Gbps
  • 1Gbps
  • 100Mbps

Logically, in order to achieve speeds of 2.5Gbps or 5Gbps we will need to make use of a router or a compatible switch with these speeds. For example, any 10GbE switch from the manufacturer QNAP supports NBASE-T, that is, if we connect this adapter we can achieve these ultra-fast speeds.

The QNAP QNA-UC5G1T has a 5GbE network port on one end, and a USB 3.0 Type-C port on the other end. Inside the box we will find a USB 3.0 type C to USB 3.0 type A cable, that is, we can connect this adapter to the USB port of a lifetime. In case your laptop or Ultrabook has a USB 3.0 port with a type C connector, you will be able to separately purchase a USB 3.0 type C to USB 3.0 type C cable. Of course, this device does not need any additional power. Since it is powered directly from the USB port when connected.

Regarding the compatibility of operating systems, this QNAP QNA-UC5G1T is compatible with Windows 7 operating systems onwards, including Windows 10, and it is that we only need to install the driver that comes in the adapter itself, or download it directly from the QNAP QNA-UC5G1T official website or Aquantia, the manufacturer of the chipset. It is also compatible with Linux operating systems with Kernel version 3.10, 3.12, 3.2, 4.2 and 4.4, and macOS.

As if all this were not enough, this adapter will allow us to connect it to a NAS server from the manufacturer QNAP to provide it with 5Gbps connectivity. If we have a NAS with the QTS 4.3.6 operating system or higher, we can connect it to a free USB 3.0 port to have 5Gbps connectivity in the local network. However, we will have some limitations that with a native port we do not have, such as that it does not support trunk links, nor DHCP server, RADVD nor static routing.

Technical characteristics of the QNAP QNA-UC5G1T

  • Supported standards: IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, IEEE 802.3an, IEEE 802.3bz, IEEE 802.3az
  • Number of 5GbE network ports: 1
  • Connector type: USB type C, but incorporates a USB 3.0 type C to USB type A cable.
  • Dimensions: 99.8 x 28 x 27.85 mm.
  • Cable length: 20cm
  • Compatibility with operating systems: Windows 7, 8, 8.1, Windows 10, macOS 10.6 onwards and Linux 3.10, 3.12, 3.2, 4.2, 4.4 systems.
  • Energy saving: Yes

Next, we are going to show you a complete video where you can see this new QNAP QNA-UC5G1T in detail. In addition, we show you how to install it and how to make the most of the speed of the local network.

Once we have seen the main features of this adapter and the complete video, we go with the external analysis of the equipment.

External analysis

This QNAP QNA-UC5G1T USB 3.0 to 5GbE network port adapter comes in a small box, since the device itself has really small dimensions, ideal to always carry it with us with the rest of the accessories of the laptop or ultrabook.

On the front of the box we can see the speeds that it is capable of achieving, synchronization speeds, since the actual speed will be somewhat lower. Specifically, this QNAP QNA-UC5G1T adapter is capable of synchronizing at speeds of 5Gbps, 2.5Gbps, 1Gbps and 100Mbps, we must bear in mind that it is necessary to use a switch compatible with 2.5G and 5G. At the bottom we have other characteristics of the device, such as that it has a metal casing to dissipate heat, it is completely silent since it does not have active ventilation, it has an RJ-45 connector, it supports Multigigabit speeds and it has a USB 3.0 type C connector. .

On the back of the box we find the compatibility of the device with different operating systems, and where we must directly download the necessary drivers for the QNAP QNA-UC5G1T to work correctly. Of course, it also informs us that inside the box we have a USB 3.0 type C to USB 3.0 type C cable, if we want to buy it separately the USB 3.0 type C to USB 3.0 type C we can do it, but it does not come in the inside the box.

On the right side we will find the exact model of the equipment, and it will indicate that it is a USB 3.0 adapter to 5GbE network port.

Inside the box of this QNAP QNA-UC5G1T, the first thing we are going to find is a short quick installation guide. In this paper-based guide, we will be able to see the different ports that we have available (5GbE network port, and a type C port), as well as a small diagram of how we should use it with our laptop or ultrabook. Logically, this adapter can also be used in desktop computers with an available USB 3.0 port.

The QNAP QNA-UC5G1T adapter comes with a small USB 3.0 type C to USB 3.0 type A cable, specifically its length is 20cm, enough to be able to maneuver with it easily without excess or missing cable.

At one end of the QNAP QNA-UC5G1T we can see the USB Type-C port, and at the other end we will have the 5GBASE-T network port at our disposal. Thanks to this device we will be able to reach speeds of up to 5Gbps, specifically we can achieve around 360-420MB / s approximately.

At the bottom of the device we will see the exact model, the certifications it has passed, the MAC address and also the serial number.

As you can see in the following photo gallery, using this USB 3.0 to 5GbE network port adapter is really easy. We will simply have to connect a Cat6 or higher network cable from the 10G switch (or Multigigabit switch compatible with 5Gbps) to the adapter itself, then with the data cable and power USB 3.0 type C to USB 3.0 type C, we will connect our computer laptop or ultrabook.

Once we have correctly connected the cables, and we have installed the necessary drivers for our operating system, we will have access to the local network, and we can see the synchronization speed that reaches up to 5Gbps.

Once we have seen in detail what this QNAP QNA-UC5G1T USB 3.0 to 5GbE network port adapter looks like, we are going to go to the test lab to check the real performance.

Test laboratory

In order to achieve speeds of up to 5Gbps in the local network, we must take several aspects into account. First of all, we are going to need a 10G switch with NBASE-T, or a Multigigabit switch. We have used the switch QNAP QSW-1208-8C, a model that meets the basic requirements, since it has 10GBASE-T ports, and supports speeds of 5Gbps, 2.5Gbps and also 1Gbps. The cabling used is Cat7 with a length not exceeding 2 meters, therefore, we have more than guaranteed speed and the problem will not be in the cabling.

On the other hand, in order to get the most out of this adapter in reading and writing, we must bear in mind that a hard disk will bottleneck, since normally a HDD has around 150MB / s speed, while this adapter promises to reach up to 420MB / s. It is necessary to make use of an SSD that will get around 550MB / s if we use the SATA3 interface, or if possible, we can make use of NVMe SSD so that we are not limited by this interface. We recommend you read our complete guide to set up a 10G network in your homes.

In our tests, we have used the Lenovo X1 Carbon Ultrabook equipped with an Intel i7-5600U processor, 8GB of RAM and a 512GB PCIe SSD, and USB 3.0 ports, to connect the QNAP adapter. We have accessed a total of three computers on the network simultaneously, and all of them connected to the 10G switch, although with different synchronization speeds since they do not have 5G cards.

In the following screenshots, you can see that the sum of the transfer speeds reaches 360MB / s:

In QNAP lab tests they have managed to squeeze this adapter up to 420MB / s, a higher figure than us, as they use more powerful hardware. You can see our complete video with the unboxing, installation of the adapter and tests below:

Once we have seen in detail the performance that this QNAP QNA-UC5G1T adapter is capable of achieving, we go with the strengths, weaknesses and final conclusions.

Strengths

  • 5Gbps network port to transfer data in local network at maximum speed.
  • USB type C port to greatly facilitate the connection of the cable to the adapter itself, in addition, we can use a USB 3.0 type C to type C cable (sold separately).
  • Achieved throughput of up to 360MB / s in our tests.
  • Small in size and with a metal casing, with a feeling of optimal robustness.
  • Compatibility with Microsoft Windows, Linux and macOS operating systems.
  • Price: outstanding. This USB 3.0 to 5GbE network port adapter is around € 100, an ideal price for a very interesting accessory for our laptop or Ultrabook.

Weak points

  • When we are doing intensive use it gets quite hot. We have the option to configure the “Thermal throttling” so that it lowers the performance automatically and does not reach high levels of temperature. We have not used it (by default it is disabled).
  • It does not incorporate a USB 3.0 Type-C to USB 3.0 Type-C cable (sold separately).

Last conclusions

This QNAP QNA-UC5G1T USB 3.0 to 5GbE Network Port Adapter is the Ideal accessory for your laptop or Ultrabook. In case you want to have an Ethernet network port, this device is a great option, since it has connectivity at speeds of up to 5Gbps. In tests we have found that we achieve speeds of up to 360MB / s, triple what we would get with the typical Gigabit Ethernet port found in laptops.

The design with metallic finish is really elegantIt has a really good feel and is very robust. The incorporation of a USB type C port to connect the cable is ideal to be able to connect it in any position since it is reversible. Inside the box we have a USB type C to USB type A cable, the strong point is that currently any laptop or Ultrabook will have at least one pair of USB type A ports, however, the new Ultrabooks already have a USB connector 3.0 type C, so we miss that they have not incorporated this type of cable inside the box as well (you have to buy it separately).

Thanks to the compatibility with different operating systems, we can use this QNAP QNA-UC5G1T on Windows, Linux and also macOS operating systems. On the official QNAP website we have links to download the latest version of the drivers from Aquantia, the manufacturer of the chipset inside the adapter.

Before finishing, we would like to emphasize that the QNAP QNA-UC5G1T gets quite hot when we are transferring at maximum speed for several minutes, in fact, the controller allows you to configure the Thermal throttling so that when it reaches a specific temperature, it automatically lowers the speed to help with device cooling. With non-intensive use, it does not overheat, only when we are transferring almost to the maximum of its capacity.

If we take into account the characteristics of this QNAP QNA-UC5G1T, the performance achieved by this USB 3.0 to 5GbE port adapter, and the price of about 100 euros, RedesZone’s assessment is 9/10.

We hope you liked the analysis, if you have any questions you can put a comment and we will respond delightedly.

review of this Fast-Ethernet to USB 2.0 adapter

With regard to the adapter, what we have to say is that it has a very small size, a very adjusted price and adequate to the expectations of users in terms of spending, leaving to check in this analysis if the performance it offers can be compared to of a physical network port. Many of you may wonder what the compatibility of this device is: The manufacturer has everything under control and the computer has a CD with drivers for Windows, Linux and Mac OS X, therefore, in principle there is no problem to perform the installation .

Before continuing, we are going to learn about some of the most significant features of this device.

Technical characteristics of the Edimax EU-4208 USB adapter

  • Supported standards: IEEE 802.2, IEEE 802.3u
  • USB port type: 2.0
  • Network port type: Fast Ethernet
  • Length: 21 centimeters
  • Compatibility with operating systems: Windows 2000, XP, Vista, 7, 8, 8.1, Mac OS X, Linux
  • Energy saving: Yes

External analysis

We begin with the external analysis of the device and also its packaging. On this occasion and due to the size of the device, the manufacturer has opted for the use of rigid plastic to create the packaging. In addition to this, inside we will find an installation CD with the drivers for different operating systems and a brief instruction manual. On the front of the packaging we can find some specifications related to the device, while on the back we find some of the most notable features of it in different languages.

With a price that does not exceed 20 euros, this adapter is postulated, as we have already advanced, as a great alternative for those users who own an ultrabook and who, due to the extreme thinness of the chassis, the manufacturer has not been able to include a network port. Taking into account that we are talking about a USB 2.0 adapter, to enjoy its full potential it is advisable to use at least one USB port of these characteristics or higher.

Regarding the content, there is not much to say, except that the instruction manual is enough to install the equipment. When installing it, it is recommended not to plug in the adapter first. First of all we install the driver that can be obtained using the CD or resorting to the manufacturer page and then after completing the software installation process connect the adapter.

In the introduction to the analysis we mentioned the word simplicity and that is what we find in this adapter. The size is extremely compact without sacrificing the protection of the cable at all, which as can be seen is protected at both ends to eradicate or at least delay the problems characteristic of this type of cables and that appear quite frequently and derived from its use. The total length of the Edimax EU-4208 barely exceeds 21 centimeters, therefore, we are faced with an extremely compact device, with a body that has a length of 6.5 centimeters. To the length we must add the extreme thinness of the equipment, further defining itself as an alternative and easy to transport if we usually travel too much or need to transport the adapter to the office, university etc.

The network port has the two characteristic LEDs that show the user whether or not there is network activity on the port. Taking advantage of the fact that we have mentioned the word “activity”, it should be noted that the manufacturer details the existence of an advanced energy saving mode, allowing the device’s consumption to be adjusted at speed. That is, if the use of the adapter is exhaustive, the consumption will be maximum, however, if we are only browsing the Internet, it will be regulated until almost reaching the minimum, allowing the device’s battery to be maximized in the absence of a power source. alternates.

To conclude the external analysis, we are going to make a short summary of what we have seen so far, being able to use two words: compact and simple. To these we will add the price of 20 euros that it has in the market.

Testing bench

The time has come to perform the performance tests and see what results we get. For our test bench we have used the following equipment:

  • TP-LINK WR1043ND
  • Macbook Pro running Windows 7 (BootCamp) and to which the adapter will connect
  • Windows 7 desktop computer

We will also use the JPerf program, thanks to which we will generate traffic that we will send between both ends. Taking into account that the physical network cards of both computers are Gigabit, we have chosen to configure the one of the Macbook from the Device Manager, eliminating the Auto negotiated and setting the value 100 Mbps Full duplex. First we will measure it and then we will connect the Edimax EU-4208 USB adapter and repeat the measurements.

The results obtained in the tests can be found in the following table:

Threads Broadcom NetXtreme Gigabit Ethernet Edimax EU-4208 USB Adapter
30 94.4 Mbps 94.6 Mbps
fifty 94.1 Mbps 94.6 Mbps
100 93.9 Mbps 94.4 Mbps
200 93.0 Mbps 94.1 Mbps
500 90.2 Mbps 92.1 Mbps
700 85.2 Mbps 88.9 Mbps

As you can see, the performance of the USB adapter is even better than that presented by the physical network card of the manufacturer Broadcom, therefore, in terms of performance we have to say that it is incredible and that to enjoy it you only you need at least one USB port that is 2.0 or higher.

Installation process

As we have mentioned before, the adapter is compatible with Windows, Mac OS X and Linux, however, we wanted to test its installation in each of these three operating systems and check if the level of complexity is as low as the manufacturer indicates.

Windows XP / 7/8

The installation in this case is guided and the user will have no problem to make it work in the operating systems mentioned in the header, both in the 32-bit and 64-bit versions. The only thing to remember is that you should not connect the adapter before installing the driver, since Windows can assign inappropriate software and even if we install the manufacturer’s later, the device will have been configured with an inappropriate one and we will have to uninstall this driver.

Mac OS X

The installation in this case is guided and graphical, which means that once we have downloaded the drivers, we just have to run the installer and wait for it to finish and then connect the adapter. In a few seconds after connecting the USB adapter it will appear in the “Network Preferences” menu.

Linux

For those more inexperienced in installations in these operating systems they will not have any problem to make the adapter work. Once the installer is downloaded, it is only necessary to run it and wait for it to finish. Once this has finished, it is only necessary to connect the adapter and wait about 30 seconds for the operating system to correctly assign the driver.

Final conclusions of the Edimax EU-4208 USB adapter

Strengths

  • performance: As long as we use this USB adapter in at least one USB 2.0 port of a computer, the performance it will offer us will be optimal.
  • Price: If to the good performance offered in the tests we have to add that for less than 20 euros it can be ours, we are facing a great alternative if our laptop does not have a network port.

Weak points

Final score

The performance offered by the Edimax EU-4208 USB adapter is undoubtedly superb and has nothing to envy that of a physical Fast Ethernet port. If we add to this that the price does not exceed 20 euros, we are faced with a product that deserves and is very worthwhile for those users who are owners of an ultrabook that, due to its extreme thinness, does not have a network port. The only thing to keep in mind to enjoy its full potential is to have at least one USB 2.0 port on your computer.

Useful, easy to install, good performance and great price, for this reason, we decided that the Edimax EU-4208 USB adapter has a final score of 10/10.

USB 3.0 Type C to Gigabit Ethernet Adapter Analysis

This adapter incorporates automatic speed detection with auto-negotiationThis means that it will synchronize at speeds of 10, 100 or 1000Mbps, depending on where we connect it, and of course, it will always use the maximum possible speed that the link allows. The adapter itself has LEDs for connection status and data transfer speed, in this way, we can know at all times the link synchronization speed and if we have activity.

As for the USB 3.0 type C connector, we simply have to connect it and we will be ready to connect to the local home or professional network, thanks to the small and compact design, it makes it very easy to always carry it with us wherever we go. Other important features of the D-Link DUB ‑ E130 are that It reduces energy consumption During light data traffic, when it is idle and even when the Ethernet network cable is disabled, this is ideal because it will not drain the battery of our laptop. Of course, it incorporates the energy saving functions incorporated in the USB 3.0 type C standard itself, and this adapter is specifically designed for Ultrabooks.

This adapter is compatible with Windows XP operating systems onwards, including of course the latest Microsoft operating system which is Windows 10. It is also compatible with macOS 10.6 and later operating systems. If you are using a Windows 8, Windows 8.1, Windows 10, macOS 10.11.6 or later operating system, you will not need to install any type of driver, the operating system itself will recognize it and we can start using it in a matter of seconds. If you do not have these operating systems, the driver software installation will start automatically as soon as we connect the adapter, we will not have to download drivers manually over the Internet.

Finally, this USB 3.0 Type-C to Gigabit Ethernet network port adapter has Wake on LAN. Thanks to this feature, if our computer allows WoL, we will be able to use this device to turn it on locally through the LAN, or remotely if we configure the network properly. This functionality is ideal if we need to access our laptop or Ultrabook remotely.

Technical characteristics of the D-Link DUB-e130

  • Supported standards: IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, IEEE 802.3az
  • Number of Gigabit Ethernet network ports: 1

  • Cable length: 12 centimeters
  • Compatibility with operating systems: Windows XP, Vista, 7, 8, 8.1, Windows 10, macOS 10.6 onwards.
  • Energy saving: Yes

Once we have known the main characteristics of the D-Link DUB-E130, we are going to go to the external analysis to see what this adapter is like.

External analysis

This D-Link DUB-E130 USB 3.0 Type-C to Gigabit Ethernet Adapter comes in a small box, as the adapter itself is really small. On the front of the D-Link DUB-E130 box we will see the main features of the device, such as, for example, that it is a USB Type-C adapter to a Gigabit Ethernet network port. At the bottom we have other features such as that it is 1Gbps Full-Duplex (something that is always the case, since the 1000BASE-T standard does not allow Half-Duplex), it has energy savings, it supports Wake on LAN, and it is fully Plug & Play now. We will not have to install any type of driver, however, if you have old operating systems, you will have to install a driver (although it will do so almost automatically).

On the back of the box of this D-Link DUB-E130 adapter, we will find the main characteristics that we have explained to you in the introduction in different languages, including Spanish. The most remarkable thing is that it supports Wake on LAN and is completely Plug & Play.

On the right side of the box of this D-Link DUB-E130 adapter we will find these same characteristics, but it also includes that it can be inserted and removed hot, that is, with the computer on. It also supports both Half-Duplex (when syncing 10/100 Mbps), and Full Duplex (when syncing at 10/100/1000 Mbps). Finally, no type of power adapter is necessary, as it is powered directly from the USB 3.0 type C port of the laptop or Ultrabook.

On the left side of the box we have the minimum requirements to run this USB 3.0 to Gigabit Ethernet network port adapter. It is compatible with Windows XP / Vista / 7/8 / 8.1 operating systems and of course, Windows 10. We will also be able to use it on Mac computers, specifically it is compatible with MacOS 10.6 or higher. It is only necessary to have a USB 3.0 type C port available to be able to get the most out of this D-Link DUB-E130.

The contents of the box of this USB 3.0 to Gigabit Ethernet network port adapter is as follows:

  • D-Link DUB-E130
  • Quick install guide
  • Manufacturer’s warranty and GPL code.

What's in the box of the D-Link DUB-E130 USB 3.0 Type-C to Gigabit Ethernet Adapter

This D-Link DUB-E130 USB 3.0 Type-C to Gigabit Ethernet Network Port Adapter has a really minimal design, it’s finished in white, and it’s really small. At one end we will have a small USB 3.0 type C cable, it is neither too short nor too long, we think it is the ideal length to fit perfectly on our laptop or Ultrabook. At the other end we will have the typical Gigabit Ethernet network port, with the corresponding status and synchronization speed LEDs.

At the bottom of this D-Link DUB-E130 we will have the typical sticker with the exact model of the equipment, the serial number, the MAC address of the device itself since it is still a network card, and also the version of hardware, which in this case is version A1. Finally, in this area we will also have the different certifications that the D-Link DUB-E130 has passed to be able to be sold in different countries.

Once we have seen in detail what this D-Link DUB-E130 USB 3.0 to Gigabit Ethernet network port adapter looks like, we are going to go to the test lab to check the real performance.

Test laboratory

The test lab for this USB 3.0 to Gigabit Ethernet Network Port Adapter is to check local network performance. In these LAN tests we will use JPerf to see how it behaves with multiple threads on the local network.

With 100 concurrent TCP threads we get a transfer speed of 113MB / s, an excellent result. The performance obtained by this adapter is exactly the same as that of a normal network card that is Gigabit Ethernet.

With 250 threads we get a speed of 112MB / s, an excellent performance. We must also take into account the router used, since if you have a low or mid-range router and it does not behave well in LAN, this adapter will not do it either.

As you have seen, the performance provided by this D-Link DUB-E130 adapter is very similar to that of a network card, that is, we obtain the expected speed. Once we have seen in detail the performance that this D-Link DUB-E130 USB 3.0 to Gigabit Ethernet network port adapter is capable of achieving, we go with the strengths, weaknesses and final conclusions.

Strengths

  • USB type C port to greatly facilitate the connection of the adapter to the computer, since it is a reversible port.
  • Gigabit Ethernet network port, which is currently typical in networks, although it would have been desirable to reach up to 2.5GbE at least.
  • Achieved performance of up to 113MB / s in our tests.
  • Small size with plastic finish, but gives a very good feeling of robustness.
  • Compatibility with Microsoft Windows operating systems, and macOS.
  • Fully Plug & Play for the latest versions of Windows and macOS, no need to install drivers.
  • Price: outstanding. This USB 3.0 Type C to Gigabit Ethernet port adapter is available for about € 35, an ideal price for a very interesting accessory for our laptop or Ultrabook.

Weak points

  • The network interface is Gigabit Ethernet, and it is not 2.5GbE or 5GbE to achieve higher speeds on the local network.
  • If your computer does not have a USB 3.0 type C port, you will not be able to use it. In this case, you will have to resort to the D-Link DUB-1312 model, which is similar, but with a USB 3.0 type A connector.

Last conclusions

This D-Link DUB-E130 USB 3.0 to Gigabit Ethernet Network Port Adapter is the ideal accessory for your laptop or Ultrabookas long as it has a USB 3.0 Type-C port, otherwise you won’t be able to use it. In case you want to have an Ethernet network port, this device is a great option since it has Gigabit Ethernet (1Gbps) connectivity, which is the typical speed that we can find today in almost any local network. In tests we have found that we achieve speeds of up to 105MB / s, an expected speed.

The design with plastic finish is quite robust, although a metal finish would have been desirable. The incorporation of a USB type C port to connect the cable to the computer, is ideal to be able to connect it in any position since it is reversible. An important detail is that you will not be able to connect this device to a USB 3.0 type A port, in case your laptop or Ultrabook does not have this type of connection, you will need to buy the D-Link DUB-1312 model.

Thanks to the compatibility with different operating systems, we can use this D-Link DUB-E130 in Windows operating systems, and also macOS. In case of having Windows 8 / 8.1 and Windows 10, the installation of the drivers is carried out automatically, since it is completely Plug & Play. The same is the case with the latest versions of the macOS operating system. If you do not have an updated operating system, you can always install the drivers almost automatically.

If we take into account the characteristics of this D-Link DUB-E130, the performance achieved by this USB 3.0 adapter to a Gigabit Ethernet network port, and the price of about 35 euros, RedesZone’s assessment is 9/10.

We hope you liked the analysis, if you have any questions you can put a comment and we will respond delightedly.

review of this Gigabit Ethernet to USB 3.0 adapter

Unlike its predecessor, of which we published the in-depth analysis, it has a Gigabit Ethernet network port and therefore a USB 3.0 port. Regarding the price we must pay, it must be said that it is slightly more expensive than the previous model, something that is understandable because it has superior performance. The price of 22 euros also makes it a device with a great quality / price ratio, or that is what we can appreciate on paper, since the performance tests will confirm this.

As usual, before proceeding with the analysis of the device, we are going to know some of the most notable characteristics of this USB adapter.

Technical characteristics of the USB adapter Edimax EU-4306

  • Supported standards: IEEE 802.2, IEEE 802.3u
  • USB port type: 3.0
  • Network port type: Gigabit Ethernet
  • Length: 20 centimeters
  • Compatibility with operating systems: Windows 2000, XP, Vista, 7, 8, 8.1, Mac OS X, Linux
  • Energy saving: Yes

External analysis

The adapter is inside a box placed in a plastic mold. On the front of the box you can see some of the most important specifications of the device, while on the back we can see the most representative characteristics of it in different languages, including Spanish. We can also see a graph that describes the operating speeds of this device.

One aspect must be kept in mind: although the USB 3.0 standard can reach up to 5 Gbit / s speed, having a Gigabit Ethernet network port produces a bottleneck and the speed is reconverted. This means that even if you connect to a computer that has 10 Gbit / s ports, the speed will never be higher than 1 Gbit / s

One of the aspects that is highlighted in this packaging is the presence of an energy saving function that allows the device to choose what energy consumption it needs to function optimally, being ideal especially for laptops. In the case of downloading files, the adapter will work at full performance and consumption will be maximum, while if we are only using the adapter to access web pages, consumption will be practically reduced to the minimum necessary.

Regarding the content of the box, in addition to the USB adapter, we can find a brief instruction manual, a CD with complementary material regarding documentation and the installer of the device drivers. Being such a simple operating device, it is obvious or at least it seems reasonable that the manual is relatively short, since there is not much to explain when it comes to the installation and commissioning process.

Referring to the installation process, it should be mentioned that in order to carry out a proper installation, the drivers must first be installed and then the Edimax EU-4306 adapter must be connected.

Regarding the device, it should be mentioned that it has dimensions similar to those of its little brother, although with a much more rounded design. In addition to the USB 3.0 port and the Gigabit Ethernet, the equipment includes LED indicators that will help the user to know at all times what the status of the device is and if it is working correctly.

The function of these indicators is:

  • Power– Indicates whether the device is receiving power, that is, whether it is off or on.
  • Speed– Indicates the speed at which the Gigabit Ethernet network port has been configured.
  • USB 3.0 connection– Indicates whether the USB connection is working properly and at what speed the connection has been negotiated.

These indicators replace those that had the network port in the manufacturer’s previous model, the Edimax EU-4208, where the LEDs were close to the network port.

Regarding the size we are talking about an adapter that has an approximate length of 20 centimeters and a body that measures 5 centimeters. It should be noted the extreme thinness of the equipment, allowing it to be manageable and easy to carry anywhere we have to go, especially if we need to travel for work reasons.

After taking a look at the physical design of this adapter, we are left with its compact design and the LED indicators, something that never hurts and always serves to diagnose possible problems with the equipment.

Testing bench

The turn has come to perform the performance tests and see what results we get. For our test bench we have used the following equipment:

  • TP-LINK WR1043ND
  • Macbook Pro running Windows 7 (BootCamp)
  • Windows 7 desktop computer

We will also use the JPerf program, thanks to which we will generate traffic that we will send between both ends. Taking into account that the physical network cards of both computers are Gigabit, we have chosen to configure the cards in such a way that they do automatic negotiation.

The results obtained in the tests can be found in the following table:

Threads Broadcom NetXtreme Gigabit Ethernet Edimax EU-4208 USB Adapter
30 937 Mbps 940 Mbps
fifty 939 Mbps 940 Mbps
100 938 Mbps 922 Mbps
200 927 Mbps 861 Mbps
500 897 Mbps 879 Mbps
700 867 Mbps 812 Mbps

The conclusion that can be drawn is that the performance is slightly lower than that of a physical Gigabit Ethernet network port, although it must be remembered that we are using a USB port, and even if it is 3.0 because at this transfer rate it is It is normal for a performance difference to appear even if it is less than 60 Mbps in the worst case. Despite everything, the performance is still excellent and we are facing a great USB to Gigabit Ethernet adapter, remembering that its price is only 25 euros.

Installation process

The compatibility of the adapter is not a problem, since as we have mentioned previously, it is compatible with Windows, Linux and Mac OS X operating systems. To verify the ease of the installation process, we have carried out the process in different operating systems.

Add that the drivers can be obtained thanks to the CD included with the adapter or go to the manufacturer’s page.

Windows XP / 7/8

For Redmond operating systems, the installation process is extremely simple. The only thing to keep in mind is that you do not install the adapter before installing the driver, since in some cases you could install a driver that is not the correct one. Once the CD installation wizard has started or the .exe has been downloaded from the indicated page, we wait for it to finish and then connect the adapter.

Mac OS X

In the case of the operating system of Apple desktop computers, we have to run the .dmg file contained on the disk or, as we have already pointed out previously, download from the manufacturer’s page. Once we start the installer we just have to wait for it to finish. After connecting the adapter, we will only have to wait 30 seconds for the driver to install correctly and we will have our USB network adapter ready to be used.

Linux

Although in many cases it may seem like a chimera, in reality this is not the case, or at least in this case. The user will have to download a file, unzip it and go to this directory through the terminal and type make. Once the compilation is done and if no errors have been returned, we can write make install and wait for the installation to finish.

Final conclusions of the USB adapter Edimax EU-4306

Strengths

  • Price: compared to other alternatives, it is a very economical option for users.
  • performance: with a performance very similar to that of physical Gigabit Ethernet ports, it is a great alternative for those ultrabook users who have an Internet speed greater than 100 Mbps.

Weak points

Final score

As has already happened with the Edimax EU-4208 model, the great performance and price of this adapter causes it to stand out from the rest, or at least from the alternatives proposed by Apple for example. Surely more than one who is reading this reflection will think that paying more than 22 euros for an adapter of these characteristics is losing money, and more taking into account the product that has been discussed in this analysis. Gigabit speed close to that of physical network ports and a simple design coupled with easy installation and compatibility with Windows, Linux and Mac OS X make this adapter a great alternative.

For all this that we have mentioned, we have decided to give the Edimax EU-4306 USB 3.0 adapter a score of 10/10.

Analysis of this network card with two 10GbE ports

The data interface of this network card is PCI Express 2.0 x8 although it is also compatible with x16 slots, in this way, we can obtain the maximum possible performance.

Some very interesting features of this network card is that it has support for 9K Jumbo Frames, support for VLANs, IPMI support, management through SNMP, performs checksum offload to TCP, UDP and IP, this means that the CPU of the The card is the one that does this work and not the main processor of the server. The D-Link DXE-820T also supports TCP segmentation, QoS, and up to three classes of CoS.

The manufacturer D-Link provides drivers for Windows Server 2008 (x86, x64) / 2008 R2 (x64), Windows Server 2012, RHEL 6.4 / 6.5 (x64), RHEL 5.9 (x64), SUSE Linux Enterprise Server 11.2 / 11.3 (x64) and Solaris 11 / 11.1. Although these are officially supported operating systems, systems like Debian and derivatives are also supported, in fact we have tested this card on Windows 7 with the WS2008 drivers and they work fine.

In addition, if you use Windows 10 Professional, you can install this card without installing the drivers from the CD, since the operating system itself installs them automatically and without having to do anything else.

The price of this card aimed at a professional market? Around 400-450 euros.

Main technical characteristics of the D-Link DXE-820T card

  • Support for 100BASE-TX, 1000BASE-T, 10GBASE-T standards.
  • 2 RJ-45 ports with speeds up to 10G.
  • Support for Link Aggregation and Teaming Port.
  • PCI Express 2.0 x8 interface.

In the following video you can see in detail the contents of the box of this D-Link DXE-820T network card and also how it is physically:

Once we know the main characteristics, we will see its box and also the network card itself.

External analysis

This professional network card D-Link DXE-820T comes in a box without any photo or silkscreen of the card, this is because the business equipment of this manufacturer is always like this. The only thing we will see is on the back of the box a sticker indicating the exact model of the equipment, the D-Link DXE-820T, along with the MAC address and serial number.

Once we open the box we will see how the network card is perfectly protected by a plastic, ideal to avoid damage to the heatsinks or fan for active cooling.

The contents of the box for this D-Link DXE-820T network card is as follows:

  • D-Link DXE-820T 10G Network Card
  • A low profile bracket for installation in small server boxes or NAS server.
  • CD with digital documentation in PDF and installation drivers for the different operating systems.
  • Declaration of conformity and guarantee.

On the front of this D-Link DXE-820T network card we find the two high performance 10G ports, of course we find the activity LEDs. We must remember that this card, in addition to having passive heatsinks, also has a fan to perform an active cooling of the main processor of this card, so we can have the operating temperature under control without any problem.

In our performance tests we have verified that this card heats up, but it is not excessive either, although the fan does sound a bit more than desirable, however, being oriented to use in servers, they are usually in a CPD with more machines so this noise will go unnoticed. You will only hear the fan if you install it on your desktop computer and have it on the table next to you.

As you can see, this card is quite large, it has nothing to do with 1Gbps cards that we can buy from this same manufacturer or others. It is clear that this is a top-of-the-range card, and a good example of this are the huge metal heatsinks and the fan they have.

At the back of this card we find all the circuitry of the chipsets on the front, which is normal for this type of card. Finally, we can change the bracket of the D-Link DXE-820T network card very easily, to use the low-profile one that the equipment incorporates.

So far we have come with our external analysis of this high-performance D-Link DXE-820T network card, as you can see, a typical network card but with 2 RJ-45 ports with 10G technology each, for what we can obtain a spectacular performance.

Test laboratory

The manufacturer D-Link has provided us with two units of this high-performance D-Link DXE-820T network card, and also a high-end switch that has RJ-45 ports with 10G technology. The switch in particular is the D-Link DXS-1100-10TS with 8 10G RJ45 ports and two other SFP + ports, we will analyze this switch soon so we wait for you on RedesZone.

Once we have installed the D-Link DXE-820T network cards in two computers, one of them with Windows 7 and the other with Windows 10, we have connected a Cat6 cable since they support 10G speeds in short distances, we do not we have exceeded 1.5 meters of this type of cable.

You have more information about the tests we carry out and the hardware used in our Testing benchIf this is the first time you see our analysis, we recommend that you read it to know how we obtain all the values. Below you have the tests and our conclusions.

Testing with the DXE-820T card

In the following screenshot you can see that the cards have been connected in port 1 and in port 8, which is in green means that they synchronize at 10Gbps without problems, and in orange that it synchronizes at 1Gbps (the router that is Gigabit).

If we go to the center of networks and shared resources, we will see the status of the local area connection, as you can see we have a 10Gbps synchronization, which we already expected. On the Windows 10 computer we also have 10Gbps synchronization.

The first performance test we have performed is to perform a transfer between a Samba server hosted on the computer with a 10G card, and another on a Samba server hosted on a NAS server connected via Gigabit Ethernet.

As can be seen, the network card is receiving data at a speed of 2Gbps together, and it is that both the hardware of our equipment and the hard drives are bottlenecking, the network card is only at 20% of its capacity.

If we carry out a test with iperf3 we can verify that we have achieved a maximum speed of 7.5Gbps when sending data, due to the hardware we are using we have not been able to achieve the 9-9.5Gbps that we should achieve under normal circumstances.

We must bear in mind that if with the hardware used we have not been able to squeeze a single 10G port, imagine using Link Aggregation with the other 10G port and having a bandwidth of up to 20Gbps. This card is aimed at servers with top-of-the-range hardware, in which we have a large number of SSDs in RAID to obtain the maximum possible performance. To give you an idea, a SATA3 interface where we normally connect SSDs and hard drives has a maximum speed of 6Gbps, and this network card is capable of providing up to 20Gbps of speed, more than triple.

In small and medium-sized businesses there is almost always a NAS server or file server with great hardware, to give ultra-fast data delivery to all employees. In this way, you will be able to squeeze the maximum speed of the 2 10G ports of this card, otherwise you will not be able to even get the most out of one of those ports.

software

The software included in this network card are the drivers for the different supported operating systems, however, we have verified that both Windows 7 Professional SP1 and Windows 10 Pro do work correctly with this network card. In the first case we had to install the Windows Server 2008 drivers, and in the second the driver installation was done by the operating system itself, we didn’t have to do anything at all.

Once you have seen the main features of this card, and the performance we have achieved in the tests, we will explain the strengths, weaknesses and conclusions.

Strengths

  • 2 RJ-45 ports with 10G speed and Link Aggregation support
  • Includes a low profile bracket to fit low boxes.
  • Ease of installation, simply click into an available PCIe 2.0 port.
  • Drivers on CD for major server OS such as Windows Server, Red Hat or SUSE.
  • It is compatible with other operating systems although it does not include the drivers on the CD, such as Windows 7 and Windows 10 (among others).
  • Active cooling to keep the temperature under control
  • Price: outstanding, it costs around 400 and 450 euros.

Weak points

  • We will not take advantage of the maximum performance that this card is capable of providing us if we do not have very powerful hardware, but is that a problem? Of course not, therefore we have not found any weak point to highlight.

Last conclusions

This D-Link DXE-820T network card is a top of the range in its field, not only incorporates 10GbE technology but also has two ports to further increase performance through Link Aggregation or Teaming Port. This network card incorporates very important features for servers, such as TCP, UDP and IP checksum offload, which will unload work from the server’s main processor, since the card itself will take care of all this. That it is compatible with QoS, up to 3 CoS, Jumbo Frames and VLANs support falls within the expected in a network card oriented to the professional market.

The performance of this card is excellent, in fact, in few cases we will be able to squeeze the maximum 20Gbps of speed from both ports. If we are going to transfer data at high speed, surely the bottleneck is found in the data interface of the SSD / hard drives, or else in the server hardware itself. In fact, it is very likely that you will have to modify kernel parameters to try to maximize the speed that this card allows you.

The price of this card is about 400-450 euros, a competitive price since it is aimed at companies and very professional users, we must bear in mind that it does not have only one RJ-45 port, but two, so we will have an extra performance that other cards won’t give you. Obviously this price for a home user will be very expensive, does a home user need 10Gbps speed on their local network? I do not think so.

If we take into account the features, capabilities and performance of this DXE-820T card and the price, RedesZone’s assessment is as follows:

We hope you liked the analysis, if you have any questions you can put a comment and we will respond delightedly.
