I use Postgres w/Vinum setup to mirror 2 9gig SCSI Cheetahs and I have
no complaints.  I bang on the db quite a bit (moderately busy site and
tons of data analysis) and performance is great.  Ultimately I am going to
slap a hardware RAID card in there (need the immediate failover) but right
now software wise performance is great.  I'd probably only recommend
doing mirroring in software though, RAID-5 is going to eat up alot more
CPU and disk writes.
