I'm going to purchase an eSATA 5-bay external enclosure (Sonnet 500P). I plan to use two of the bays to stripe two drives together for fast scratch space (Photoshop, iView, Stitcher etc).

I was pointed to Microdirect as a place to buy SATA drives. I was going to get any old 160GB 7800rpm SATA2 drives, but I found Western Digital Raptor drives (designed for RAID, 10,000rpm). I used to edit video (back when SCSI was standard on Macs, a while ago!) and 10,000rpm drives were de rigueur.
Would two Raptors be overkill for what I need? (among other things, I regularly work with Photoshop files that get up to 1.5-2GB in size, and the single SATA drive I use for scratch in my dual 2.0GHz G5 really struggles).
Thanks for any insights,
