    could this be correct way ?


    originally posted in this thread about a kernel PnP warning showing in Event viewer. Kernel-PnP warning

    I stated i kept getting this warning in 100's in my event viewer, plus PC go into boot loop on restarts only and that part was solved with BIOS update. Also stated as long as i had this system with Windows 8.1 Pro 64bit my USB 3.0 speeds were very slow.

    With Windows 8.1 i saw this and read about the Intel USB 3.0 eXtensible Host Controller Driver that Win 8.1 uses it's own, Intel does not supply one for 8.1 or 8. I have Microsoft Driver that i am sure most have with Win8.1
    http://Intel® USB 3.0 eXtensible Host Controller Driver

    I felt this was reasoning with my USB 3.0 issues, the driver. Gigabyte possibly thought might be the board.
    When using a USB 3.0 External Hard drive i am getting between 50mbs -100mbs ,even slower then USB 2.0, tried different drives and tested each.

    Question is i came across a thread in a forum on researching this problem, someone said to go to Disk Management when drive is hooked up, right click the drive and select Properties, then select Policies. Under policies 2 choices, Quick Removal (Default) and Better performance, first one disables write caching and second one enables it. Said to select Better Performance.

    Seems when i choose Better performance now my USB 3.0 has incredible speeds on USB 3.0, some as fast as 2GHZ transfer, some at 1.36GHZ.

    Question is is this correct to do, i see internal drives are set this way, but enables write caching now on External ?
    Instead of pulling the USB 3.0 device from port, do i have to then use Safely remove hardware in Notification area instead ?

    Looks like my speed issues are fixed, not sure of these settings.

    Definitely will increase speed but definitely need to use safe removal if enabled. Sometimes data to be written will sit in the cache until you safely remove it, then it will write after you click and then will let you know it can be removed. Not doing this can result in corrupted files.

    PS: I would not check it for your internal HDD.

    Alright, so you mean removing it first from the notification area, then unplug the drive ? I believe i get what you mean by doing this way prevent corruption in files. Not sure if this is a correct resolve to USB 3.0 issue, sure is fast now, never heard of 1.36-2GHZ speeds on USB 3.0 !!

    Oh, does not show same for internal drive even though SSD's, even checked on my internal HDD, see in pic, assume of course write caching is enabled by default for these.

    Update, came across this, i know i have this option in BIOS but i had tried it i believe before BIOS update and did not make a difference to USB 3.0 Speeds. About closest thoughts of resolution i can get, talking to Gigabyte now think maybe the external drive, which i tried more then one with same result, except when i make the change now in Disk managements, policies tab, for the drive.

    Gigabyte tested one of same boards and said had no issues with USB 3.0 devices, felt might be the drive, even though tried different drives.
    Resolve i posted earlier that helped they told me was o.k. to use if it helped. Also article from Intel talks about enabling xhci in BIOS, in my BIOS it is set to Smart Auto, again Gigabyte said no settings need to be changed in order for it to work right. I have tried changing this in BIOS from Smart Auto to Enable, it did not make a difference anyway, but this was before BIOS update i did.
