    Very slow USB transfer rate on win 7 64 bit


    Hello
    I'm using win7 for a while and i never noticed the transfer speed of usb bcoz i've never transfer a huge files before. The transfer speed is only between 3-4 Mbps and nothing more. Ubuntu atleast gives me 7-10Mbps. Recently I transfered 400 MB folder and it took 30 - 40 min at the rate of 250kbps. The 400MB folder was my XAMPP folder which contains multiple files.
    I got pretty frustrated at this. Please help me find a solution to this . The other day i was late to office bcoz of this , it took 40 min as described above.
    please provide some insight to this. I'm expecting at least 15-20 Mbps

    Thanks In Advance

    Format your USB Drive to NTFS with 8192 bytes of assignation, after the format, go to Device Manager, open hard disks, right-click your USB drive and go to Properties, the 2nd tab to the right (from your left), should say "Directives" (sorry about that, i have a spanish version of Windows 7) and check the "High Performance" module.

    That will solve your problem

    You should probably try to find the specs for your drive.
    I just researched a Kingston Data Traveler 2 Gb USB Drive.......Data transfer rates of up 6MB/sec. read and up to 3MB/sec write.

    Try what Punkster and Mike mentioned, but most importantly look for the data transfer specs.
    15-20 Mbps may be unrealistic on some drives.

    Didn't think about that, P5! you're completely right, but the method of NTFS formatting and High Performance Directive will give the USB a really good improvement, that's how i have all my USB's and they work just fine.. 2GB files and only takes a couple of minutes...

    But you'll never get higher speeds than advertised from the manufacturer, you'll only get "close enough" heheh

    Two days ago, I bought a 64 GB Sandisk flash drive to use for copying my Windows 7 Qozmio 770 series 64-bit laptop files onto for backup purposes and to load onto an old second computer. I had originally purchased the 16 GB model, but a Tom's Hardware review convinced me to get the 64 GB model for its transfer speed.

    I think I may have deleted the .exe file (Secure Access??) because I'd been told to do that if I didn't want the flash drive to do automatic stuff; or else it wasn't there to begin with (it's referenced in the manual).

    I started to copy my 3 GB Documents folder, consisting of 35,000 files (16XX folders). The first few minutes looked normal; then the speed steadily dropped into the KB range, where it remained. I canceled the operation.

    Because I had never copied the full documents folder from my laptop onto a flash drive (the full folder was only on my desktop until recently--I don't recall how long it took to load it onto my laptop from my WD external HD.)

    I tested two flash drives and all three in different ports, 2.0 and 3.0, and the results were the same, with transfer speeds reaching a high of 1 MB/sec. Optimization for documents didn't help. Downloading a Toshiba USB driver didn't help. I've read that a 16 GB works better for small files than a 64 GB does, but my older flash drive didn't transfer appreciably faster.

    My laptop is almost 3 years old and out of warranty; phone support wants $49.95 to help me. Is there anything that I, a non-guru, could check? It appears not to be the flash drive, as I originally thought.

    Down load and install USBDeview. This program allows you to do some basic trouble shooting. Make sure the USB 2&3 drivers are up to date.

    Size does matter, generally larger is faster. With a system configured correctly even a 2-8gb class 4 SD card should move at 8-10Mbs in USB 2.0 and around 20Mbs in a USB 3.0 port. USB 3.0 pen drives are close to 200Mbs. These are bench test numbers, actual file transfer is slower.

    The USB chip on your MB makes a difference. If you are going to be moving lots of files you may want to install a e-pci usb card with a better chip set.

    How do I make sure the drivers are up to date? I have now found the USBDeview page and skimmed it, so I see that will at least list my drivers--don't know yet if they'll tell me if they are or aren't up to date. I'll install it.

    Chip sets are beyond my understanding. I don't know where to go from here. Also, in System Information, there is nothing listed under Ports: Serial, Parallel. It seems as if there should be, since I do have USB ports and they are working. Sort of . . .
