    Slow write speed


    Hi, best wishes for 2019!

    I've noticed lately that my writing speed is quite low.
    I mean when I copy/paste a large file from one disk to another, or from one disk to an USB external HDD.

    Things I tried already:
    - Disk Cleanup
    - Ccleaner
    - DISM.exe /Online /Cleanup-image /Scanhealth
    - sfc/scannow
    - chkdsk /f /r c: & also my External HDD

    No problems found in each individual operation.

    Quick system specs:
    Windows 10 Pro 64 bit Version 1809 Build 17763.195
    OS, Drivers, and most of my Software is fully up to date.

    Any ideas, tips or tricks to increase my write/read speed?

    :)

    Slow Download Speed

    Hi,

    Thank you for posting your query in Microsoft forums.

    • I would suggest you to test the speed using any of the speed test website or app to confirm the upload and download speed.
    • I also suggest you to reset the wireless router to check if that helps.
    • You may plug in the Ethernet cable if available and check the speed.


    Hope the information is helpful. Feel free to write to us for any other assistance with Windows, we’ll be glad to assist you

    Slow write speed

    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 ...
