I don't wish to continue a pissing contest, only to correct the flow of 
misinformation.

Are you suggesting that RAID is _the_ answer to HA+ solutions?  I work 
with fully dynamic failover designs utilizing clustering software 
(Veritas VCS, RAC, BitKeeper, etc), multipath software, clustered 
hardware (redundant SAN switches/controllers), etc.  RAID does not 
fulfill the role of any of these components, nor was it designed to.  
It is an integral part of a solid HA+ design, but only one small part 
of the overall schematic.

Secure transmission features, like those I mentioned earlier, are also 
integral to designs where the data store must be kept separate from the 
HTTP server (say, any e-commerce site).  If this type of feature wasn't 
needed, I doubt the MySQL folks would've bothered to put it in.
