What about arrays of lower cost consumer grade SSD's vs the more expensive
"enterprise" drives or cards.  The 'I' in RAID can stand for "inexpensive".
It can make sense to mirror two cheap drives on non-big data server
applications.  So the HD form factor for solid state storage is a good thing
in this case.

Two 60GB SATAIII drives for $45/ea is really cheap.  $60 for 120GB.  Wow.
