I'd suggest avoiding RAID 5 at all costs with a database. You're going to take a huge performance hit with the parity calculations, especially with more input that read. (6) 36 gig disks probably isn't where you want to be, as spindle speed (and number of) is crucial to performance. Your best bet is to stripe and mirror (RAID 10) or don't apply any raid level, and distribute the database over the disks properly. Make sure and mirror your redo logs though.
