This key provides the high capacity we needed while remaining compact. Good protection against impact and relative tightness. You just be careful not to lose the cap, systematically putting it in a pocket for example. This is not the fastest of the Corsair brand. Without having accurate measuring means of speed, the Corsair Voyager GT 128GB 3.0 (red / black) and black Stealth 128GB Voyager 3.0 are judged much faster. I recommend these products, and this one in particular because it works nickel and is more compact hair than the other 2 mentioned models and more economical to purchase.
