This is quite a controversial question with proponents of both strategies. I would suggest having one RAID-1 array for the WAL and throw the rest of the drives at a single big array for the data files. That wastes space since the WAL isn't big but the benefit is big. If you have a battery backed cache you might not need even that. Just throwing them all into a big raid might work just as well. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
