Well for one thing, if 2 drives fail and it doens't get a chance to 
rebuild, then I still have 2 good drives.  Another thing is if a drive 
fails and the spare is in the wrong location, and the spare becomes the 
boot drive, it won't be able to boot, but if all 4 drives are copies of 
each other, then everything is well and good.

I don't see why I can't pull out 2 drives out of this install (like 1 
and 3), put them into another machine and let it rebuild itself.
