Windows 7 Slow Transfer of Large Files To USB Drive RRS feed

  • Question

  • I get speeds of 7-12MB/sec to my USB 2 Drive on Windows 7. I recall speeds of around 80MB/sec on Windows XP or is that my memory going sour.  I have several USB 2 Drives and all seem to be slow. I don't remember them being that slow on Windows XP though its been about a year since I upgraded.

    To increase the speed I turned off "Windows Search Service" and "Remove Differential Compression" according to advice found on the net.


    My Specs

    • Windows 7 Ultimate with all latest Update
    • Powerful PC with 16GB or Ram (Don't really know specs in detail)
    • USB Drives are all USB 2 with different Makers. None of them have fragmentation and all formatted with NTFS.
    • Drive Policies are set to "Better Performance" instead of "Quick Removal"

    Is there anything else I could do to increase transfer speed.

    Thanks

  • Thank you updating the Motherboard Drivers seem to have done the trick. I now get 60-80MB/sec  :D

  • Also, look into the USB drive's Properties/Hardware tab/Properties/Policies tab/Removal policy. The default in Windows7 appears to be "Quick removal".  XP was similar to "Better performance" (also need to "Safely Remove Hardware" with this policy).

    FMI look at Ronnie Vernon's answer in "Safely Remove Hardware, is it needed anymore with SD Cards and USB thumbdrives?"
