Doh.  Of course I meant *RAID 1* mirror.  It's an off-by-one error :-)
(I knew what I *meant* to say)

Mike is completely correct - RAID 0 "striping" is done to increase
performance at the expense of reduced overall reliability.

RAID 1 substantially improves reliability at little or no cost to
performance (actually, read performance can be substantially
better, write performance slightly worse).

Personally, I strongly recommend running a RAID 1 pair as the
"system drive" in general.
