The Micro Vault Click has a claimed read speed of up to 82 MB/s, no official figure for write speed is offered by Sony, usually a bad sign. User reviews indicate that this drive has a write speed of between 8 and 13 MB/s and that the real world read speeds are in the range of 50 - 80 MB/s. With these sorts of speeds this drive is considerably worse at writing than a lot of USB 2.0 drives. I won't do a complete review for this drive as it would be a waste of time, there are far better value for money USB 3.0 flash drives available elsewhere including Sony's own Micro Vault Mach.
