So you'd be suggesting, two 10000pm Raptor drives, 150GB each... in a Raid 0 array?
So I run the OS, and all my programs off this, and then just have one enormous backup drive for everything else (my backup of the scratch disk, and also my Archive of Files that I'm no longer working on)?
What, in three words, would be the benefit of this set up, ove just using one 10000rpm raptor as my scratch disk?
