According to a summary of the different RAID levels that I have, RAID 3 uses "parallel access" where all disks participate in in every I/O request. This would result in high data transfer rates but slower I/O request rates as only one request can process at a time. RAID 5 on the other hand uses independent disk access so separate disk access requests can be satisfied in parallel. It then says, "... this is more suitable for applications that require high I/O request rates and is less attractive for applications that require high data transfer rates."

Just exactly how all of this applies to Oracle is your guess. I could see arguements for both sides.
