Average Bench: 5.44% (553rd of 622)

Based on 485 user benchmarks.  Devices: VID 0951 PID 1689, VID 0930 PID 6545, VID 0930 PID 6544 Model: Kingston DataTraveler SE9

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]

The SE9 is stylish, well made and less than £10. You won't go far wrong if you like the way it looks. If speed is important to you steer well clear of this and go for one of the more recent and significantly faster USB 3.0 alternatives.

This drive is great to look at but if speed is important to you then it would make more sense to go for a USB 3.0 speed drive, they are far faster.
