We had high expectations for this drive, unfortunately we were slightly disappointed. On the positive side the drive has excellent sequential read speeds, but the performance profile is unbalanced and the drive is significantly weaker at writing. In terms of build quality the drive is lacking, the plastic feels loose and the drive rattles when you shake it. Overall this drive has above average performance but is also priced higher than average leaving it reasonable value for money at best, there are better deals to be had at this time. [Jun '12 USBFlashPro]

USB 2.0 is old tech, so in terms of performance this drive is less than half as fast as its USB 3.0 counterparts. Interestingly the 4K write speed is reasonable at 0.4 MBps. If you plan to move a lot of data to and from the drive you will be much better off with one of the faster USB 3.0 drives. That said, the SE9 has a beautiful form factor and is both rock solid and relatively light making it ideal for use on a keyring. [Nov '12 USBFlashPro]
