E-X520-DA1-10G-1S

Bought four, used four, worked great, no issues

I recently upgraded my PC with the Euqvos 2.5Gb Network Card, and let me tell you, it's been a game-changer! Installing it was smoother than a buttered ice slide - even for someone who's more comfortable with a keyboard than a screwdriver.The Realtek RTL8125B Chip is like the wizard behind the curtain, casting spells that make lag disappear faster than my hopes of ever becoming a professional pancake flipper. My internet speed is now so fast, I'm pretty sure my cat believes I've somehow harnessed the power of feline teleportation.I used to have more buffering circles than a magician has rabbits, but now my streaming experience is smoother than a jazz sax solo. I can binge-watch my favorite shows without the dreaded pixelation monster rearing its ugly head.The PCIe magic that this card brings to the table is like upgrading from a tricycle to a rocket ship. I half-expect my computer to start greeting me with "Welcome to the future" every time I boot it up.But let's not forget the real star of the show - the 2.5 gigabytes of networking goodness. My data now travels faster than gossip in a small town, and I've never felt more connected (pun intended). It's like my computer went to networking school and graduated with honors.In conclusion, if you want to turn your digital life into a high-speed, low-drama sitcom, the Euqvos 2.5Gb Network Card is the ticket. It's the upgrade you didn't know you needed until you realize that waiting for things to load is so last season. Get ready to surf the internet like a pro and laugh in the face of buffering. Euqvos, you've earned a permanent spot in my PC Hall of Fame!

There are many many ways to dip your toe in to 10gbe networking in your home lab for the fun of doing it.Going with a card like this is one of them. I won't go into the rest of the details but with the cheap switches out there and then running cat6a or 7 cabling, its a cost effective way unless you just want to be fancy and use fiber. either way i'm speaking from a homelab perspective.this device does identify itself as an Intel chip set. There no windows 11 drivers stock so MAKE SURE YOU KEEP YOUR CURRENT NIC ACTIVE to download the latest driver for this card. It runs cool and runs as expected. I will never reach full 10gbs speeds with my setup but i can fully saturate my solid state drives and my Raid 10 NAS with minimal effort. Which was my end goal. Literally the I/O on my storage devices are my bottleneck now. and that makes me happy.

For clarity's sake, this is specifically for the single port SFP+ 10G NIC.I'm using this in a TrueNAS Scale server and this card works without fuss. TrueNAS picked it up immediately, no fussing with special drivers or anything. I'm using it with an off-brand DAC cable to a no-name 2.5G/10G combo switch and everything is coexisting peacefully. The build quality is good, and it comes with both the full-height and half-height brackets, which is nice. No manual or anything, but lets be honest, if you're getting a 10G SFP+ NIC, you probably don't need a manual anyway. The lspci command on Linux does confirm this as a proper Intel NIC as well, it's not a Realtek card in disguise or anything, and in case you're worried about it phoning home to some server somewhere, the Pi-Hole on my network confirms that it doesn't. For the price, it's well worth it.

Adapter does work plug and play but wont get full speeds, be sure to update this (and all other NICS) to their latest drivers. Mine defaulted to decade old drivers from windows but got the latest 2024 Realtek RTL8156 (PCIe) drivers and now have full speed.

I've been using this NIC for the last 2 months on my UDM-SE without any hitches or glitches.Although I am not a network expert, and I rarely play games (only an occasional Elite Dangerous or NMS round), I have never had any issues with latency or dropped packets, or anything that would bring attention to the NIC.It's a fine card, especially at this price, and I would recommend this upgrade as an entry level NIC to anyone wanting to make use of your ISP's higher level speeds without breaking the bank.

Update: The seller reached out and refunded the purchase after reading my review. I appreciate the refund, but I'd still be up the creek if I hadn't left a poor review. Upon researching, it seems most of these RTL8125 NICs face issues sooner or later. So do the Intel I225's. I'm currently waiting for an Intel I226 version to become available. Moral of the story: I should have just gone for 10 gig.I upgraded part of my home network to 2.5 and 10 gig for Christmas. Everything was great for a couple weeks. My 2.5/1 gig switch began having issues with slow traffic on all ports. Switching cables seemed to help, but problems returned. I finally had time to really test the issues today. Running iperf3 from my Ubuntu machine with this 2.5g NIC to my Truenas machine on 10g looked great on the first run. The following tests were progressively worse. Cable changes and running cable to my 10g switch directly made no difference. Switching back to my onboard 1g NIC remedied the issue immediately.The first picture is my main NAS to my back up NAS with 10g connection. Solid, no noise. The second is my workstation to back up NAS with this card. Abysmal speed with a ton of noise. The last picture is after switching back to onboard NIC going through both switches and all original wiring.Verdict, junk card. I'll be finding a more reliable product to replace this junk with.

Easy install, speed tests shows it works perfectly.
