again, thats really a raid-10 regardless of what your disk controller 
calls it.

sure, we do it all the time, mostly for relational databases such as 
Oracle, where we will use 4 or 6 spindle raid10's as tablespaces (and 
often many sets of these for a large volume trnasactional database server).


but, whats recommended really depends on what you plan on using it for, 
and what your IO performance requirements are.
