if anything I'd put the the database (and especially tempdb) on RAID10 and the logs on RAID5, the reason being that the database will have some small writes (8kb) while the logs will always write 64kb or greater pieces so you can set your stripe size to 64kb and be assured of full stripe writes.
I know the 3PAR throws most things out the window but that seems counter intuitive since RAID10=best for writes, RAID5=slight advantage in reads so wouldn't it make sense to put the DBs on the RAID5 and the Logs on RAID10? Also, why can't I set the stripe size to 64kb in RAID10? The option is there to do so.
