 	I normally chime in at this point in such discussions.

 	I'm running RAID1 raidframe on just about all of my NetBSD
 	boxes, even dedicated servers. The only exceptions being
 	laptops and the occasional test scratch box. The slowdown
 	for a parity rebuild in the case of an unclean shutdown is
 	annoying, but otherwise I've been extremely happy with the
 	result. Maybe that would be a nice SoC project...

 	I'd recommend getting disks from different vendors of ~
 	the same size and picking the smaller size for the raid -
 	reduces the likelyhood of two disks failing at the same
 	time (thankyou maxtor). The only time I break that rule is
 	with WD Raptors, but for the massively better seek times
 	I'm prepared to compromise :)
