Query: Very useful USB2 drive

This 500 GB drive works well with a Mac via USB2, and is very quiet. For a Mac, there's no installation of drivers and no software required, it just works (like everything else on a Mac ;-). I've used it with two different Macs without problems. The USB2 interface is slower than Firewire 400 in actual use, but as a backup drive it's more than fast enough.
