Review: Got full 10G speeds - It works and works well with those SFP+ cables that are cheap from desertcart.
Review: Good card, with a slight catch in Windows 11 - Great card so far. Works with either fiber sfps, 10G copper sfps or with DAC cables. One caveat with Windows 11: I had to find and install the older Intel x510 drivers for it to be recognized and work. Linux (Pop OS 22.04 LTS) had the drivers and libraries available natively. As far as stability and connectivity is concerned, zero issues so far. A quick Google search found an old Redfit article with a link to the driver pack, so 10 minute fix.

## Features

- Compatible with Windows Server 2003/ 2008/ 2012, Windows7/8/10*/Visa, Linux, ESX/ESXi*. Storage over Ethernet: iSCSI, FCoE, NFS. (Only by setting up Win10 driver correctly the NIC can work on Win11! See the main picture for more detail of installation.)

## Questions & Answers

**Q: What's the difference between the x540-t2 and x550-t2 ?**
A: The X520 and X540 have a PCIe 2.0 x8 interface, which has 32Gbit/s bandwidth.
The X550 has a PCIe 3.0 x4 interface, which has 32Gbit/s bandwidth.

The single-port versions may be used in slower slots: X520-T1/DA1 or X540-T1/DA1 will work in a PCIe 2.0 x4 slot (at 16Gbit/s); the manual says the T550-T1 should work in a PCI 2.0 x4 slot as well, although I haven’t tried it.

**Q: Has anyone actually gotten close to the 10gbps connection speed for this card?  pcie 2.0 has limit of 5 gt/s or about 4gpbs max.  so can it be 10gb?**
A: The card is PCIe 2 with x8 lanes, which is 4 GigaByte per second. 4 GigaByte is the same as 32 GigaBit, so it should handle 10 GigaBit just fine.

**Q: Will this card negotiate down to a pcie gen 3 x2?  i think my only free x4 slot only runs in x2 mode which is why i'm asking.**
A: No, please kindly note that the X550-T1 supports PCIe v3.0 (8.0GT/s) (Compatible with 2.0 and 1.1) X4/X8/X16 Lane, and it does not support X2.

**Q: does this work with windows 11?**
A: I have not gotten it to work with windows 11. The seller says to install drivers 26.7 but those dont work

### ⭐⭐⭐⭐⭐ Works great!
*by C***N on February 14, 2020*

I bought 3 of these cards for a couple Synology NAS devices (DS 1618+ and DS 2419+) and my main computer, mainly for faster media transfers and an attempt to edit 4K footage direct from my NAS in real time. The price is significantly more expensive here than buying direct from 10GTek and having it ship from HK and used NICs are apparently very cheap if you look around. I installed the cards in my computer and the DS 1618+ to start with. It was a painless experience and the small form factor bracket was easy to switch on for the Synology. From a networking standpoint there are many ways you can go about it. I opted for a Mikrotik switch with 4 SFP+ ports, which made things a breeze. You can plug directly from one device into another if they both have a 10Gb NIC but you'll need to do some configuration with static IPs. With more than 2 10Gb devices you'll want to get a switch. In terms of cabling, I was only doing short distance networking (7 meters max) so I went for SFP+ DACs. You can also network with a transceiver and RJ45 if you have an existing CAT6 or newer setup, or a multimode fiber, which is good for longer distance networking. The Synology connected to the internet & LAN immediately upon being switched on - completely plug-and-play. My computer wasn't and I don't have a DVD drive so I had to try to find the drivers online. You can essentially treat this as an Intel NIC for most intents and purposes so I went to Intel's website and downloaded the Intel® Ethernet Adapter Complete Driver Pack. That was useful because it not only installed the drivers I needed to be able to connect but also gave me tools to test that the connections were working properly. I've only done one test so far but immediately saw 3-4x transfer speed improvements. Before I was seeing about 113MB/s, bottlenecked by a 1Gb connection. I saw high 300s MB/s during a file copy from my NAS to my SATA SSD, equating to about 3Gb speeds. Your bottleneck will now be the speed of an HDD array or SATA (6Gb). You can achieve even faster speeds with NVMe to NVMe transfers. Overall, definitely happy with this card so far. Seems to be completely plug-and-play for most people.
