If you're writing data to the raid in large contiguous chunks then it you get higher bandwidth than RAID1+0. The problem with RAID5 is that if you're writing random access chunks then it's even slower than not having a raid at all. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
