I think the simplest and most generic solution would be to put the OS and pg_xlog on a RAID 1 pair and dedicate the rest of the drives to RAID 5 or RAID 1+0 (striped set of mirrors) array. Depending on the nature of your work, you may get better performance by placing individual tables/indices on dedicated spindles for parallel access. -Mike Adler ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
