Designed for people on the move, the LaCie PocketDrive is small enough to fit into your pocket and features a special silicone bumper and sturdy casing for proven shock protection. New USB 2.0 interface delivers significantly faster transfer rates of up to 480 Mbits/sec, while still allowing you to connect USB 1.1 devices. LaCie PocketDrives incorporate the latest chipsets available, ensuring transfer rates of up to 25 MB/sec (write) and 35 MB/sec (read) when using FireWire interface. Using LaCie's unique U&I technology, the PocketDrive incorporates both USB and FireWire connectors, allowing you to swap from one computer to another without rebooting.
1 Died after 18 months
My LaCie 20gig Pocket drive died after 18 months. I used it once per month for backup of my desktop system and laptop. Now it's green light comes on but it doesn't spin up and the USB connection will not be recognized by either system.
2 Expensive but small and reliable
Bought a 60Gb version of this drive 2 years ago and have travelled the world with it ever since. Small, reliable, fairly robust (owing to the shock-proof rubberized casing) and with the convenience of both firewire and USB 2 interfaces. Plug it into Win2k, it gets auto-recognized and you're good to go in a few minutes. Windows explorer shows it as just another drive in the system. The second and subsequent times you connect, it gets set up even faster since the drivers will have been already loaded. Superb way of carrying 60Gb or more literally in your pocket.
If you are on the move a lot or want to extend your laptop I'd highly recommend it. However, the price per Gb with this drive is somewhat high, so if you could live with a less portable drive, then there are cheaper drives available with larger capacities. If size / weight are an issue, then I can recommend this as a very portable and reliable solution.
