The Kingston DTR500 came Amazon typically rapidly. Thanks! Now to the memory stick: This is one of the fastest drives I've ever had in your hand! I have long hesitated whether my USB stick is worth so much money, but after I read in the computer image that only expensive and is really good at the mobile store, I simply dared times. And I was not disappointed! The stick comes almost to the manufacturer's instructions of 30 MB / s read and 20MB / s write (measured with MacOS, Activitiy Monitor R 27 MB / s and W 23 MB / s). Normally, the real values are far beyond the marketing promises. Ok, the design is a matter of taste, but somehow the stick also looks sleek. The cap is secure and can be plugged at the foot, so you do not loose during use. The attachment eye is large enough to secure the stick on a key chain. A blue LED indicates read and write activities of the sticks on (flashes, quite bright). All in all I'm very happy, so full five stars!
