I'm writing this as a warning for buyers. These are everywhere, the white 64gb toshiba flash drives. I just brought one and tested it, it only holds 4gb. Which is a noticable difference. I regret leaving a positive feedback for the guy as he asked for it when I asked for a refund. At that time I did not know it was a blatant counterfeit, just thought it was faulty. Since then I ran some tests. Will post test results shortly.
