  We use PostgreSQL on a hardware RAID controller, RAID 5.  Our system has
never had a stability problem in the 1+ year that it's been running, so I
turned off fsync().  Between the 64 megs of cache on the controller and a
gig of disk cache on the machine, the lights on the drives blink
*occasionally*.  I don't consider RAID 5 to be a problem at all, at least
not in this situation.  Our $12,000 machine will beat the $25,000 Alpha
that a Compaq rep loaned to us.  : )
