Even RAID-5 is okay for usage scenarios like data warehouse where you're more concerned about read performance than write performance. For OLTP, if you move your redo logs to a RAID-1 array and just use the RAID-5 for data files, I think performance won't be too bad either because most of the writing to data files happens in the background.
