H!Fiber.com 10G Ethernet network card,SFP+ NIC,10GbE CNA,function compatible to X520-DA1,with Intel 82599EN controller,support Windows Server/Linux/VMware (not support MAC)

Installed in my PC to talk to my 10gb ubiquity agg switch. Works well, need to install the drivers from intels website before it will work.

Great upgrade for my synology nas

Bought this to go into my PC to link to a Synology NAS via a Unifi XG Switch. It all just works without any messing with anything. Running windows 10 latest build.

Good product

What an absolute waste of time. No driver for windows 11 and absolutely rubbish. Requested return after wasting over one day of life.

Super

April 28, 2026 Update: I've been using these network cards from OPNsense version 23.7.10_1-amd64 through version 26.1.2-amd64 with no problems. The performance and reliability have been superb. Original December 31, 2023 Review: Using a fresh OPNsense install (version 23.7.10_1-amd64) this network card was detected right away and I had no problems installing and configuring to work with OPNsense. I have two of these network cards, along with two of the SFP+ RJ45 transceivers listed below, installed in a custom PC used for a router; the transceiver worked great with this network card (I needed a transceiver that could auto-negotiate at 2.5Gb). https://www.amazon.com/dp/B089CWVHX4 I don't have a 10Gb home network setup yet, so I was only able to test up to 2.5Gb for home network; this network card worked great. I have 1Gb+ internet service and had no problem consistently achieving 1Gb+ download speeds with this network card and transceiver. I was previously having performance issues with network cards that used RTL8125B chips and I225-V chips. I saw a number of OPNsense forums mentioning these X-520/82599 based network cards are reliable, reasonably priced, and have OPNsense/FreeBSD driver support, so I wanted to try 82599 and see if that solved my performance issues. So far it has been great and I wish I would have started with this configuration instead of wasting so much money on other network adapters.

This is not plug and play, you need to find the correct drivers for your OS for the Intel controller that it uses. That isn't as straightforward as it could/should be. Once set up, it certainly can work to specification but I have found some odd performance behaviours that get rectified by enabling/disabling other ethernet adaptors on my system. Very odd. But overall, I'm satisfied.

Funziona perfettamente. Utilizzata per il mio NAS
