I think that is well worth a debate.
As Bob points out, these storage arrays do not have redundant hot-swap
PSUs, or hot swap disks.
They're made for the market for large volume online archiving - where
you would imagine that there 
are two or more copies of data in geographically separate locations.
Is it time to start looking at the cost/benefit analysis for 'prime'
storage to have the same scheme?
Don't get me wrong - I have experienced the benefits of N+1 hot swap
PSUs and RAID hot swap disks on many an occasion,
as has everyone here. There's nothing more satisfying then getting an
email over the weekend about a popped disk on an array
and being able to flop back onto the sofa.
