Connection to the computer
The big advantage of this drive is its size. This means it blocks itself no different USB port. This problem could occur, however, if you have the USB flash drive to a key ring, then you can over / underlying ports use only limited.
Use of USB sticks
The extent to which the stick is really waterproof and resistant to dust and shock, I can be hard to assess. And I want to test it even better. ;-)
The drive runs with me both under XP, and Windows 7 very well. I had no problems so far.
Speed of USB sticks
The speed test of the USB stick had with me the following results:
Write rate: 9,44Mbyte / s
Read rate: 24,5Mbyte / s
