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 With Fireware Mac it works great!
As the previous reviewer noted, dependence on AC adapter power is funky. The plug doesn't fit tightly at all!
However, the Pocket drives are both USB and Fiewire. So once I got mty firewire Macintosh, the drive has been great! On a Mac, the Fiewire connection powers the Lacie. I don't think this is the case for PC, though not certain.
2 Did not work consistently
I bought this to back up key data files on 3 computers, 2 are Win 2000 and one is a Win 98SE machine. At first the unit would not power up, either the AC adapter was faulty or the internal plug connection was lose. Tech support was very knowledable and helpful. They sent me a new adapter and I had power although sometimes I had to jiggle the plug at the hard drive end. I never was able to get it to work on all three machines, it worked on one Win 2000 and the Win 98SE machine. Even on these 2 machines it did not work all the time, it seemed very moody. I returned it before my time was up for returns.
Next I bought a Kanguru Quicksilver and I am much happier with it. It has easier to use set up software and it is working well on all 3 machines.
