Even though I have been using the hardriveKINGSTON FLASH MEMORY for only a couple of days so far I am convinced that it was a great purchase.
It comes in an extremely appealing shape - very slim, light and small, seems to be of very high quality and is fast enough for daily use. If you use a rather old computer with low USB KINGSTON FLASH MEMORY power supply the single USB cable might be too less to run the drive; consider buying a Y-cable or a new computer then. For everybody else it's the better solution because the drive occupies only one plug. The delivered cable is short, however, that means better portability.
The software is not powerful but still very useful. As long as you don't expect more than scheduled daily backups for specific files you should be fine. Mac users might go for the Apple version since it offers FW 400/800 and is a lot faster therefore. It's a bit thicker and heavier though... KINGSTON FLASH MEMORY
