What I keep hearing through various back channels is that, if you pay
folks from Veritas to look at your installation, and they see RAID 5,
they suggest you move it to 1+0.  I haven't any idea why.  It could
be just a matter of preference; it could be prejudice; it could be
baseless faith in the inefficiency of RAID5; it could be they have
stock in a drive company; or it could be they know about some strange
bug that they haven't an idea how to fix.  Nobody's ever been
able/willing to tell me.
