In a RAID, all data goes across all disks, so in your case the answer is no. I doublt tablespaces would help, because again all data goes across all disks. What you might consider, if you can break up the RAID, is to use two disks for a mirrored pair (RAID-1). Put the WAL logs (the pg_xlog directory) on that volume. Then make a RAID-5 with the other four disks for the rest of the database. The pg_xlog directory is constantly written to so having it on independent disks is very helpful with performance. -Doug ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
