    Item as described, fast shipping, recommended seller. I got 2 NICs. One for my Truenas file server and one for my Proxmox VM host, creating a direct connection between the two systems. Running iperf3, I managed to get 23.5Gbps.

    Powerful, yet not expensive.

    I bought 2, for Proxmox and Truenas. In a direct connection between the two I managed to get around 2GB/s transfer rates. Depending on your hardware and tuning of course.
