So what you're saying is:
1. Reliability is not important.
2. There's zero write traffic once the database is set up.
If this is true, then RAID-0 is the way to go. I think Greg's options are
good. Either:
2 discs RAID 1: OS
6 discs RAID 0: database + WAL
which is what we're using here (except with more discs), or:
8 discs RAID 10: everything
However, if reliability *really* isn't an issue, and you can accept
reinstalling the system if you lose a disc, then there's a third option:
8 discs RAID 0: Everything
