    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.
