Nowadays, USB drive has definitely become one of the major medium
through which data is transferred to and from the computers. But, you
might have notice that sometimes you feel like data transfer speed
should be more. Although, it depends upon the type of USB drive that is
being used and its performance, but still there are many ways by which
one can surely improve the performance of the USB drive. One of such
solutions has been recently introduced by Microsoft which has been
specially designed and developed for the Windows 7 operating system.
