Vogzone 25GBE Dual-Port SFP28 Network Interface Card with Mellanox CONNECTX-5 EN Chipset, PCI Express 3.0 x8 Ethernet Adapter Compare to MCX512A-ACAT

Bought this for my Unraid server in a small Jonsbo N3 ITX case, and I'm very happy with it. Worked immediately with no drivers required, getting consistent speeds and no drop outs or any abnormalities. It does get hot so I'd recommend adding a fan near it. Using a TP-Link SFP+ RJ45 10GbE to a TP-Link 10GbE switch with no issues. Huge improvement when accessing my server from other PCs on the network.

It’s a 25G dual Mellanox dual Ethernet/rdma card for $100. Seems to work just like the name brand ones. I’ve run it at 25G with direct sfp cable, and 1G with sfp to rj45. I think it does not do 2.5G/5G

Used it as I didn't have an extra pcie slot available on my ITX based unraid server. Was recognized immediately and the performance is as expected. The only downside is the cable supplied is very stiff.

Works great on Proxmox running on an AMD 9700X box with an MSI X870 motherboard, and achieves ~9.5gbit/s between devices through Ubiquiti network hardware over Cat6A; however, be weary of modular SATA power cables. This was my own fault, so no stars deducted, but upon initial installation, the machine refused to post. When I'd power it on, it would instantly shut off. So, taking a step back, I thought through what the problem might be. My power supply (Corsair RM850x) didn't come with enough SATA power cables, and I had made the incorrect assumption that a SATA power cable is a SATA power cable. I grabbed a left-over one from an older EVGA modular supply that I use elsewhere. This is how I learned that modular power supplies do not have standard pinouts across manufacturers. So make sure you're using the correct SATA power cables for your power supply.
