You'd need to name some names here for this to mean too much.  There are 
plenty of positively miserable RAID controllers out there.  I wouldn't 
trust the cards from Adaptec, Promise, and Highpoint to correctly store a 
database about what's in my pockets.

Here you're hitting on the real point.  If a proposed solution adds 
potential for database corruption if someone trips over the server cord, 
it's not really a solution at all.
