    Everything works like intended, no problems under Proxmox 8 and with Ubiquiti 10/25Gbps DAC connected to Mikrotik switch. NIC was packaged in plastic "box" with low-profile adapter in separate compartment and was in superb condition.

    Item was in really good state might as well have been new. Surprised me to see the thermal paste was still very liquid, maybe a repaste or the cpu just doesn't get too hot. Tested and works fine, at least for 10G SFP+. No complaints here

  • It's working on my QNAP TS-464.

    I am using it with my QNAP TS-464. It works perfectly. I am getting transfer speeds of close to 10Gbps, at less than half the price of genuine QNAP products.

  • 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.
