I got the LaCie d2 Hard Drive Extreme with Triple Interface
USB 2.0, FireWire 400, FireWire 800 160GB | 200GB | 250GB
As the ideal portable desktop drive for professional needs such as video, audio, photo imaging and data backup, the LaCie d2 Hard Drive Extreme with Triple Interface reaches a capacity of 250GB, a speed of 800Mbits/s and offers the fastest chipset generation. This powerful drive provides the convenient and universal triple connectivity of USB 2.0, FireWire, and FireWire 800.
Although this is not as portable as the porsche version it runs quite quietly and for £153 you cant complain with that amount of storage.
