Actually, RAID 5 and RAID 0 offer similar performance when using a hardware RAID controller. The CRC calculations are done by the controller, so while the RAID 5 array will perform *slightly* slower, you should never notice the difference. Plus, you still get redundancy, which is the point in the first place. RAID 0 is only appropriate for the irrationally optimistic.
As for DBs, my day job includes doing DBA stuff for several Microsoft SQL Server machines. Microsoft recommends RAID 5 for the data and RAID 1 for the transaction logs if you're looking for the best performance.
