I have the 64GB version and come when copying films or large files on average, depending on the hard disk from which the product is to be copied to 180-200 MB / s. I wanted to believe really at all, because you'll also from the normal USB 3.0 sticks s is used only lame 30MB /! That's why I highly recommend him. The slide mechanism is well and slips when eg in the somewhat narrow TV USB input does not return as in the example with my 2Transcend JetFlash 760 32GB Flash Drive USB 3.0 "the case.
