Your boss shouldn't be making implementation decisions.  If you mirror 
striped volumes, then you have to rebuild an entire half of the mirror 
when you replace a disk.

On a 4 disk array it shouldn't matter much, but I wouldn't be surprised 
if it doesn't work because that's not considered the "right" way to do 
things.

I recommend at least *trying* to create a set of mirrored volumes and 
then striping them, to see if that configuration works.
