Of course you can measure transfer speeds; These things I have not done. My personal requirements, some dubbing of larger amounts of photographs or MP3 music, it is just; the speed is to my taste fine. The stick is pretty small and falls otherwise neither positive nor negative (about very quickly or very slowly). It's just a standard USB flash drive to transfer data at an acceptable rate. This I did not expect when buying and also bekommen.Somit I'm satisfied.
