    Morning All,

    A weird one but i have the following hard drives in my laptop;

    Running Windows 10 Pro.
    main Drive (256GB M.2 NVMe PCI-E SSD).
    2nd Drive (1TB 7200RPM SATA 6G).

    When i copy a large file from my main drive to my NAS, i get consistent 40MB/s. This is as expected for the NAS i have.

    When i copy a large file from my 2nd drive to my NAS, i get around 1-2MB/s. This is too low.

    When i copy a large file from my 2nd drive to my main drive, i get around 95MB/s.

    The issue only happens when i directly copy files off the 2nd drive directly onto the network, happens with other NAS's on the network too.

    There is something fishy going on but cannot fathom what. Any takers?

    Cheers
