I always go for RAIDframe and RAID-1; disks are free compared to labor
hours.  I have used it for a long time, probably 2001ish, and it's been
solid.  One of the benefits is that a NetBSD kernel with EITHER of those
disks in any random box will work.  With a hardware RAID approach, you
need that particular controller.  So if you do hardware raid, and you
care about availability, I'd have spare of all the hardware on hand.
