The Scratch disk is what PhotoShop uses to allow undos and keep track of the history. Every time you do something to your image, it records the previous version on the scratch disk -- or at least enough information so that your next step can be undone. The bigger your scratch disk, the more history steps you can save. And a bigger scratch disk allows you to work with bigger files. Obviously, the speed of the disk being used as a scratch disk is crucial. With a huge firewire drive, PhotoShop flys. Paul
