There have been some discussions about which hardware suits PostgreSQL's
needs best under certain load-characteristics. We have experienced quite
a write-performance burst just from switching from a RAID5-config to a
RAID10 (mirroring&striping), even though we had been using some
supposedly sufficiently powerful dedicated battery-backuped
SCSI-RAID-adapters with lots of on-board cache. You can't beat simple,
although it will cost disk-space. Anyway, you might want to search the
archives for discussion on RAID-configurations.
