I don't know about cheap. Sure disks are less expensive than ever, but it
is usually that you get bigger disks for the same money - try buying a 2G
or even 4G disk from Sun these days.
By the time you have the number of spindles you want and the number
of controllers they need you typically have 2-3 times the storage space
you want and the disk sub-systems represents a decent percentage of
system cost. Even on my p166 here, the disks add up to about 50% of
total cost of the system (not including the monitor).
But yes, we tend to use raid 0+1.
