    Marvell 91xx slow disk write


    Gigabyte B75M-D3H motherboard
    Windows 10 1803

    Accessing the disks works fine.
    But writing is at USB 2 speeds.

    In Device Manager -> System Devices it is listed as Marvell 91xx Config Device.
    The driver is latest (checked various ways.)

    In Device Manager - Storage Controllers it is not listed.
    DriverFinder shows it as not having a driver.

    The Marvell Tray Utility seems to be happy with everything.

    Just very slow write speed.

    I have seen other post in the forum showing it as listed under Storage Controllers, so I was wondering ...

    :)
