Hi,
there are different versions of RAID.

I can't remember the name for the version I was talking about, but this version stripes data across, say, five discs and ends up with performance from the scratch disk that is as fast as RAM - so you can end up with the performance equivalent 80GB of ram for photoshop.

Amadou's book talks about this and a friend up the road, who has this setup, told me about the speed equivalence.
