Everyone here always says that RAID 5 isn't good for Postgres. We
have an Apple Xserve RAID configured with RAID 5. We chose RAID 5
because Apple said their Xserve RAID was "optimized" for RAID 5. Not
sure if we made the right decision though. They give an option for
formatting as RAID 0+1. Is that the same as RAID 10 that everyone
talks about? Or is it the reverse?
Thanks,

RAID5 generally doesn't bode too well for performance; that could be
part of the issue.
