PCIE X4 Interface to 10GbE SFP+ Fiber Port Ethernet Adapter for Gaming, Network Surfing, Intel 82599EN 10 Gigabit Ethernet Controller, 10GbE PCIE NIC Card, 10GbE SFP+ LAN Adapter (X520-DA1)

Works great. I needed a 10g connections for my NVR server. Great value, and once you install the intel drivers it comes right up. I am happy that it uses Intel OEM drivers and not have to use the shady CD that comes with it. Just search for Intel 82599ES and download the driver pack for Win10 family "Wired_driver_30.0.1_x64.zip”. Then go to device manager and manually update the driver and point it to the driver pack folder. Installation is easy if you have swapped out a nic card before. Highly recommend if you need a single 10g link for your PC.

Super easy install, 10GBe works great. All I did was add a 6COM SFP to RJ45 to it and download the Intel drivers as described in another review here. Works much better than my old stock 1GBe ethernet.

This card is solid. Plug in your SFP and you are ready to go. 10Gbps at this price is a deal but when you factor in the build it is more than worth it's asking price. Made with an Intel Ethernet Controller as well. It's not some cheap knock off. It comes with a low profile bracket for easy installation in an SFF situation or in a server. Full functional for a fiber network or ethernet depending on the module you insert. You will get full speed full duplex 10Gbos functionality. Blazing speed for today's most demanding networks. Great value for the dollar here.

I tested this in a Proxmox (Debian based Linux) and a Windows 10 machine. Both had drivers built in and recognized the LAN card without issue. I don't get the full 10GB speeds, but that's to be expected considering this is using an older chipset. Either way, it works for what I need it to do, which is provide a direct connection between my desktop and my NAS.

Works great on proxmox. I haven't had any issues.

I've been using the FebSmart X520-DA1 for a few weeks now, and it's exceeded my expectations. The 10GbE connection has given me lightning-fast access to my NAS, making it feel like a dedicated server. The adapter is easy to install and the drivers are compatible with my Windows machine. I've also been impressed with its reliability and performance under heavy loads. Overall, it's been a great investment for anyone looking to upgrade their home network.

10/29/2024 : I received an SFP-to-Ethernet adapter ( https://www.amazon.com/dp/B0DHKNZDTP ), so I was able to install the card physically in my computer (Windows 10). It is not plug and play, so make sure you download the drivers from intel (search for X520-DA1 drivers). Download the "Intel® Ethernet Adapter Complete Driver Pack". For windows, unzip the file, then as per included instructions: "Navigate in your extracted files to \APPS\SETUP\SETUPBD and then the Windows subfolder corresponding to your version of Windows (32-bit or 64-bit). Inside the Winx64 or Win32 folder, double-click on SetupBD.exe." Installation took a couple of minutes for me, I did not require a restart, I plugged in my ethernet, it shows as a 10G connection on my switch. I did not think the setup would play nicely with the 5Gb card on my NAS, but using crystaldisk I show a good 5Gb transfer speed, on par with what I get with my tp-link 10Gb pcie card! Excellent pcie and adapter pair!10/15/2024 : I am in the process of setting up a 10Gbps network, and this card looked useful for the option of SPF. It is well packaged, and looks good quality. Should not heat up like the RJ ethernet versions do, so it is appealing. Will update once I have enough material to test everything out.

This 10g SFP+ card uses a the well known high quality intel 82599 controller chip that has been around for a long time. Just about every operating system has built in drivers. It did come with a driver disk but I didn’t need it. The only minor downsides to this controller is that is uses slightly more power than newer PCIe SFP+ controllers, and it uses an older PCIe version, 2.0. For most people this is not going to matter.The firmware is not fussy about SFP+ module brand, so it should work with just about anything. It is recognized as a PCIe x4 card as expected. The speeds I saw were in line with other 82599 based cards that I already have.The only issue I encountered, was that the bracket did not fit my system without modification. Basically the “ears” at the top of the bracket needed to be shortened 1-2mm. The system I tried it in has very little room for the top of the bracket, so not everyone will need to make this modification. Fortunately I have a benchtop grinder so it was easy to remove the bracket from the card and shave it down a little, this could also be done with a metal file.
