I'm thinking about putting a RAID 0 in my 15" unibody MBP. Right now I boot off of a ExpressCard 48GB SSD, which is really fast, but of course it's not that big. I figure that the array would be quite good at handling large swap files, but I don't believe OS X will just use other drives mounted in the system, but I wondered if I could ask it to do so, much like you can with scratch disks in Photoshop. Ideas? Thanks!

Back in the early days of OS X I remember I had my swap files on a dedicated HDD partition too. It was as simple as editing a config file and including the new path. No idea if that stuff still works. But there's for sure still some way to do that. Have you tried google?

I'd leave the swap on the SSD, since it'll be fastest there. Unless you're getting huge swap files.
