The figures relate to the 64GB version. On the positive side is that the stick the manufacturer's information regarding the reading and writing performance not only comply with but even offers. In maximum of the stick has reached me read speeds over 150MB / s and write speeds over 50 MB / s. Measured with ATTO Disk Benchmark and CrystalDiskMark on a Win 7 64bit PC. What surprised me the rubberized housing ". In my opinion, the case is not rubberized, but is made entirely of rubber. The stick feels like an eraser. Whether you like that everyone has to decide for itself. The rubber housing has advantages and disadvantages. Advantages the case does not go as quickly broken when the stick is falling down or something down. For instance, the cap completely from wabbeligem rubber and has absolutely no solid core. advantage they will not break if it occurs. Subjective disadvantage she does not sit particularly firmly on the USB connector. The cap can be put on the back, if the stick is used. Here, however, the cap is still labbriger. The eyelet for a Keychain is also completely made of soft rubber. Whether that holds long remains to be seen. Otherwise the drive still has a blue LED that indicates the operation. Something else to the dimensions. If you, like me, two horizontal USB ports directly next to each other has in tight spaces. But one can measure previously. All in all I am satisfied with the stick, if it considers now far all is well.
