I will add to this that I am using a partition on my hard drive
exclusively for Photoshop scratch. As I am working with base image sizes
up to 29MB, the partition size is 400MB. This works well as it gives
Photoshop a large, contiguous space in which to run its VM scheme and,
quite frankly, I am going to give Photoshop whatever it desires. Be
mindful that I am doing this on a Mac and am using FWB's Hard Disk Toolkit
to create my hard partitions; using anything other than Casablanca's Drive
7 or HDToolkit will not give you the hard partitions you need.
