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

Easy to install, value for the money, great speed. The machine I have this on is a custom-built desktop running Windows 11, and I had to obtain the driver from Intel. Great product!

My system already had 10Gb ethernet, but I disliked the heat from the translation between SFP+ and RJ46 so I got this so I could just use a DAC cable between my system and the switch. No issues installing, I just had to download the driver from Intel and install it manually, otherwise it worked pretty quickly without issues. Tested getting full 10-gig speeds through iperf3 no problem. 10Gtek seems to be establishing themselves well in the industry. Great cables, wonderful adapters, and now solid NICs to add to the list of items of theirs I've gotten and used. All work solid and as expected.

Works great, very little setup needed on my Ubuntu Linux device

I don't know what it is, but I have the WORST luck with my gaming towers. Even now I'm unable to get it to wake from sleep correctly, requiring me to wake, then force power off, then power on, then click Exit because it goes into the BIOS, restart, and finally login. EVERY TIME I try to wake it from sleep. Anyway, that's something else. The point is, I was dismayed (but not surprised) when my first X710-DA2-based card would not work. I spent hours trying to figure it out, but ultimately I gave up. I think with my luck such as it is, I just happened to get a dud. But this one works great. I did the usual dance for Windows 11 that I had become so accustomed to while trying to get the last one to work: Install to PCIe slot, reboot, install X710 drivers from the Intel website, and that was it! Plugged in the transceivers and it instantly negotiated a 10GbE connection with my switch. I then ran the Intel NVM Update utility to update the card to the latest firmware, and all is good. Oh, and a note to those (like me) that may not have memorized the data sheet for your motherboard -- on mine (MSI X670-P) the fourth PCIe slot is shared with the fourth M2 slot. So if you have several NVMe drives and that fourth slot is populated, nothing you put into the PCIe slot will work. Luckily I figured it out pretty quick and moved it, but it's something to look out for.

Good card, works “ok” with Windows 11 but better in other OSes. It keeps me from having to use the awful built-in Marvell NICs on my motherboard that seemed to slowly fail if the PC went to sleep or if they were active too long or got too warm. We live in the future!

10GTek is now my go-to brand for high speed networking. I had previously purchased their SAS and Fibre channel cables for other projects and was always satisfied with the quality. I recently upgraded many of my security cameras to 4k, You'd be surprised how quickly several 4k cameras recording 24x7 fill a Terabyte and how slowly that data moves off-system even at 2.5gb Ethernet. In order to reach my retention goals I bought these cards and SFP+ transceivers to build a point-to-point high speed link to dump footage from my NAS to a second system which uses OpenCV to take a frame from the video stream of each camera every hour to create an index so I can quickly narrow down a block of time to retrieve for review should the need arise then off-loads it all to an LTO Tape Library. I Installed these cards in two Ubuntu 25.04 systems and the native drivers immediately recognized them. I established IPs and routing and the speed I could move large blocks of data is incredible. With large file transfers the card gets warm but not incredibly hot which people had indicated should be the case with optical vs copper SFP+ modules. While SAS and Fibre Channel are incredible connectivity options in their own rights there is something satisfying about moving a similar volume of data using normal protocols like tar and rsync. I briefly brought one of these card connected to my NAS up under Windows 11 and although it is completely unnecessary the speed is addicting, now I'm looking for a good inexpensive 10gbe switch so I can put a couple more hosts on my 10gb subnet.

Drivers for Windows 11 took an hour to find and required downloading the entire Intel network driver set just to get it installed. Constantly disconnects/reconnects every 5 seconds, so the driver is faulty. Worst of all even when connected via 40gb fiber to a machine across the room it didn't get over 1.2gbps. I'm assuming the Windows driver is at fault, and it may work fine on *nix, but this is just unacceptable. Intel needs to work with Microsoft to get the driver situation fixed so that end users don't have to deal with this kind of crap - it's not like we can troubleshoot things like we can on Linux. We have to endlessly read forums with unpaid volunteers telling us to run chkdsk over and over and over again. Replacing with NON-intel network devices. I'm looking forward to at some point never using Windows or any other Microsoft product ever again. Others who are using this device with Windows - server os or otherwise - verify your actual network throughput using iperf3.

Worked great for a dual 10G connection from my server to a UniFi switch. True plug-and-play on my Linux build. Much more affordable than the local retail options and the build quality is top-notch. Highly recommend for any home lab or server upgrade.

Prodotto funziona, su scheda madre ASROCK RACK SPC621D8, VMware 7.0.3. verifiche arriva a 9/8Gbs di trasmissione.

In meinen TrueNAS Server eingebaut und sofort hat alles funktioniert. Ursprünglich wurde sie jedoch für meinen Windows 11 PC gekauft, aber dort bekam ich sie nicht zum Laufen. Wurde weder im BIOS noch in Windows erkannt. Nach mehreren verzweifelten Stunden habe ich es aufgegeben und die Karte zurückgeschickt.

La tarjeta funciona perfectamente a 10 Gb

Excelente producto

Die X520 Karte wurde in meinen TrueNas Server eingebaut, direkt erkannt und läuft mit 9,2Gbit/s stabil ohne Verbindubgsprobleme.
