Do you have a Flash Stick? Yes, of course. Do you know, how fast it is? Will you be able to run program from within it, play a portable Call Of Duty or just quickly copy a film from/to it? You don't know.
When you are going to buy a USB Drive or Stick, you can see a big amount of different vendors, and everywhere is labeled "The BEST". Who is the best? Kingston or Kingmax, PQi or SanDisk, Transcend or Canyon?
With SpeedOut you can quickly find out the speed of your Flash Drive by pressing a single button.
