I don't recommend placing online redo logs on RAID5 devices due to their
write-intensive nature and RAID5's typically poor write performance. I
also encourage you to use Oracle's multiple log group/multiple log
member per group capability as Oracle doesn't know you're using RAID and
can't automatically take advantage of RAID mirroring as it can with
multiple log group members.
