Partly, I think, people who've used both hate 0+1 because of the
recovery cost.  In most 0+1 arrangements (I'm aware of none which
don't do this), you have to re-sync the entire thing in case you lose
even one drive.  Performance really suffers at that point.

I remember when computers were frustrating because they *did* exactly what 
you told them to.  That actually seems sort of quaint now.
