Review: Fast cheap 25/10/1 Ethernet/rdma with dual ports - 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
Review: Lets you connect to remote drives at local speeds - Used two of these to connect between my NAS and desktop PC. Both machines are running on Windows and neither had an issue working as soon as the network card was installed. My devices are relatively close so I am currently using DAC cables. In testing a file share in between my NVMe drive on the NAS and local PC I was able to get a transfer speed of 2.24GB/s, around 2,240 MB/s or ~19Gbps without any network adjustment or tuning whatsoever. The NVMe drives should be a bit faster than that but this was good enough for me, until I get more remote NVMe storage only a fraction of my data is available at these speeds anyways.

### ⭐⭐⭐⭐⭐ Works as expected.
*by S***R on July 9, 2025*

I've bought around sixteen of these and they've all been solid. I don't have any brands/models to compare them to. So, I don't know if they could be any better. Nevertheless, I'm getting pretty close to full 25GiB in speed tests. I'm using these with Mikrotik switches and 10Gtek transceivers.
