GREAT! FYI, I just recently bought a 120 MB USB and Firewire external hard drive from Amazon.com for about $180. I use a laptop for all my school work and have been backing up all my data every couple of weeks to a desktop. That proved cumbersome. Since I was running out of drive space on the laptop, I decided to get a bigger drive. When I saw the price on this device (SimpleTech SimpleDrive HDD), I snapped it up. It's works great with all our PCs.
