    USB 3.0 slow read & write speed


    Hello,

    I have 4gb and 16gb kingston DT 101 usb....both had slow read & write speeds on fat32(defulat format)..
    -write speed 4-6mb/sec
    -read speed 25mb/sec appx

    When i format it to NTFS, it writes initially at 100mb/s and then suddenly slows down to appx 15-20mb/s... and sometimes it gets stuck somwhere in the middle or on 99% and when i cancel it it start cancelling but doesnt end up, and end ups by removing usb or by logging off... when i copy from usb to harddisk in ntfs format, its working f9...

    Why there is problem in writing???

    Any help will b appreciated... Thanx in advance

    (I have dell inspiron n5520 core i5, 4gb ram, with win 7 ultimate 64bit... my laptop has usb 3.0 ports (all 4 ports).... i have updated drivers and windows... i have also set my usb to better performance from device manager... there is no problem sign in device manager)

    Those DT 101 are USB 2.0 drives, they will only go at USB 2.0 rates. USB 2.0 at beast is about 35 MB/s on reads but typically 25 MB/s. And these 4GB 101 are not particularly good performers:

    The Kingston site specs say 10 MB/s read, 5 MB/s write.

    If you want USB 3.0 speeds you need to get good USB 3.0 sticks.
