10Gb Network Card Intel X520-DA1 Ethernet Card PCI-E NIC(E10G42BTDA), with Intel 82599EN Controller, Single SFP+ Port, 10G PCI Express LAN Adapter Support Windows Server/Windows/Linux/Vmware

My use case is a personal development network with two high end desktop workstations, one with AMD Ryzen 9 and the other with Intel i7. Both are running Ubuntu Linux 22.04.2 PRO and I am using a Mikrotik CRS306-4S-1N switch. Both Desktop systems have dual 10G NICs and cable into the switch with 6COM 6C-SFP-10G-T SFP+ 10G RJ45 Adapters and CAT8 cabling. As soon as everything was plugged in the systems came right up and everything was fast and sweet. Don't forget to plug in the backhaul cable from the switch to your in-house network feed otherwise no DHCP and the 10G connections don't com up. Highly recommended. This is plug and play and the most practical sense. Installation time was about an hour and that include putting boards in two machines, running cables, attaching adapters and installing switch. "Settings/Network/Ethernet/Wired/enp11s0f0 showed connected at 10000 Mb/s immediately. My one extra thought though is that the dual channel boards are only a little bit more, and by the time you bother to open up the box and install a board, you might as well think of the future, IMHO.

Was a little worried if this card would work with Windows 11 or not, but it does. You just have to download the full driver package which as all the drivers for Windows, Linux, ect. and unzip it into a folder. Then go to the device manager and select the device and click on upgrade driver. Then just point to the folder and BAM it finds the driver for Windows 11. Don't know which driver it liked, but who cares, Windows 11 likes it and it now works and tested at almost 10g speeds.

It should be noted that this chip set is no longer supported by Intel, while Linux supports the drivers, and they work great, there are no windows 10 or 11 drivers. The company's website only directs you to the Intel website drivers, which only have drivers for BSD, windows 7 and a couple of Microsoft servers. But with some internet searching, you can find drivers for Windows 10, which work perfectly fine on Windows 11. I found some on a Dell support website. That's why I give them a 4.

Works perfect on Windows 11 PC

Its not supported by Intel's firmware updates... Sad really. And win11 won't recognize it at all. It's a shame, but it works fine on Linux as far as I've tested it

Works great - up to advertised speeds. But - once I setup a vlan on this card - if both are used at the same time - the performance suffers. Guessing related to buffers. But I’m done troubleshooting.

I have this installed under Xigmanas, and it was pretty much plug and play. It has been stable, and I know it handles uploads from two 2.5gbps sources concurrently just fine. I haven't tested beyond that. It is simply packaged, and was quick to install.

I was looking for a 10Gb card to install in my windows 10 workstation and well, this one works very, very well. Installed it physically, inserted the driver CD, installed the driver and bingo I'm off to the races. This was a good purchase and I'm very happy with the performance.

Works great, you need to install the drivers on windows 11 manually by downloading them from the website, you can either Google the product name or just scan the qr code on the network card. Getting 8.7Gb speed, but this is cause my ISP provides that much. Very satisfied with this network card.
