Seagate Cheetah 15K.6 RAID 0 Scratch disk for Photoshop

I just picked up a new Mac Pro (with Apple's RAID card) & I think i'm going to run two Seagate Cheetah 15K.6 as a RAID 0 Scratch disk for Photoshop speed. I think the 156GB drives are all i'll need as far as size goes. Does anyone have any experience with this configuration?
