I use this USB stick very surprised both as my OS on the go as well as a data carrier for my files (games, music, videos) and am both on the speed of USB sticks as well as the appearance, because I have such a big difference to USB 2.0 have not expected. It has far exceeded the rate of 10 times faster. The only Markel is that one gets from the 16GB only 14,8gb to file deposit. Despite this Markel it is a very good disk and can recommend it without hesitation. I'm considering even know if I'm going to get the same USB flash drive with more space.
