I have a bootcamp'd XP partition, but it's only 32GB and I have programs like ProTools, Cubase SX, Dark Age of Camelot which are taking up a lot of space. I have about 3GB left on the drive, which slows down read and write speeds. How efficient is it to run these programs from a USB 2.0 drive? I know Firewire is a lot better, but I have a 250GB external drive that runs on USB 2.0 I'd like to have the Windows Partition as free as possible.
