Yeah, what he said.  However it is sometimes possible to get decent
performance anyways from a hardware RAID5 device if the controller has
enough cache (ie. a LOT).  Generally speaking the Oracle "suggested
layouts" for disks consist of 17-22 spindles, mirrored, with logical
splits among the write-ahead log, the data area, and the redo log...

Boy do I ever Not Miss working with Oracle.
