10Gb PCI-E NIC Network Card, with Intel 82599EN Chip, Compare to Intel X520-DA1, Single SFP+ Port, PCI Express X8, Ethernet Converged Network Adapter Support Windows Server/Windows, Linux, Vmware

I used this to connect a NAS to a 10GbE switch from Unifi via a 2 meter DAC cable and it went off without a hitch. I loaded iperf3 on my PC and the NAS to test throughput and was getting 9gbps or more right off the bat. I originally had a used mellanox NIC in this NAS which, while cheaper initially, started to have some odd performance issues over time, so I am very happy with this replacement. If you play the used lottery you might be able to get a bit more bang for your buck, but this card is very cost effective for a new in box solution.

This needs an additional piece that is missing for fiber connection. It would be best to contact company and determine everything needed for use before ordering. Once we received all pieces it was easy to install and has been working with no issues.

I have this card installed in my NAS Server that I use mainly for Plex Media server but also planning on using for local back ups.I have it installed in a 4x slot so I'm not sure I'm getting the full speed out of it but it shows connected at 10gb Full DuplexI've been using it for a couple months now with no issues.

Took me a little longer than I had anticipated getting this installed and going. Also still waiting for my 10Gig connections for NAS, as its still stuck at 2 1GB links. However I got a second NIC and tested and the throughput makes me giggle. Upgrading my network for NAS specifically for my plex server was the purpose, and it's fast as advertised.May get an additional one for another box as this worked like a charm ans the price is great.Pros:- Fast- Easy to installCons:- None

I tried to use the Broadcom card earlier on my Dell T40 Server and it did not work plus it was producing a lot of heat. This card based on Intel 8259 chipset works flawlessly in my Dell t40 server. I connected this to my USW-pro-48 using SFP+ DAC. I was able to test close to 9000 Mbps (I have Qos On) from my HP server with a 10G card to this T40 server using a locally hosted openspeedtest server. This card is not the cheapest but pretty much all cards with similar specs are in the same price range. the card comes with both low and standard profile brackets. Overall very satisfied with it and would recommend it for 10G connectivity.

Moving our network over to all fiber has been interesting. When it came to the PCs we needed to stay within our planned budget so we decided to try this network card. It installed easily into an Intel I5 PC. Windows 10 found the new hardware and installed the drivers without any problems. The 10 GB transceiver we installed worked flawlessly with the network card. Network speed went from 1 GB on CAT cable to 10GB with the fiber network card. Very impressive speed increase.

I picked this card up to add to a custom-built server that I have setup as a Proxmox Backup Server. With no additional drivers or tweaking the card was recognized right away. I used an HPE-branded DAC cable to an HPE 10Gbps capable switch and I was up-and-running at full speed in a flash. I can now backup my entire home lab in 1/10th the time it used to take! Card came with the bracket and screws for a half-height slot, which was awesome. Overall, very pleased with this adapter.

This is an Intel X520 wired server adapter that can negotiate a 10Gbps link. Rock-solid link to my other equipment. You may need to download the drivers from Intel's website because Windows 11 doesn't seem to ship with them.
