I m thinking of buying a new external hard disk for my desktop. So is it require some different port in desktop for usb 3 or the traditional usb port are enough.

And in any case, since you have a desktop PC you can always install a PCI USB 3.0 card to take advantage of a USB 3.0 drive's better performance. Can't find your answer ? Ask !
