16GB SanDisk Extreme USB 3.0 SDCZ80-016G-X46 (Accessory)
I use this USB 2.0 key and no worries. Finally high transfer rates (24MB / s with me) that allow me to quickly copied files. I spend eb 2013 USB 3.0 so it will be able to move on to the next level. The key has no cap and sliding system works well.

Already a good experience of USB 3.0 but there is at record speeds sometimes exceeding 70 Mbs. Very pleased with this key (perfect ergonomics, almost too light) and especially the price. (19)
