Very small and fast yet.

The stick of SanDisk is how the picture suggests, extremely small. He's fast, CrystalDiskMark spits 132MB / s read and 45MB / s write off at USB3.0. If USB2 are read 35MB / s and 23MB / s write. The stick has a small, red LED that flashes slowly by the Sandisk logo at the stick, when writing to the drive. If nothing is written, the LED goes out smoothly and on. Well. 4 stars has the stick get because the cap very, seehr stuck. Without nail or a special technique you spend several minutes until you have separated the stick from the cap. Advantage: The cap also does not go lost on the way. Some USB ports of the stick lifts fixed it, but in this case it is still far enough out that you can pack it well and pull out. Power, what is recommended, a small string to the stick (holding device available, see pictures), you get the stick from the slot easily and in seconds from the cap.
