Correct.

Sure.  Configure your LUNs with a capacity that does not exceed the capacity that would be used if everything were RAID-1, and everything will stay in RAID-1.  In other words, AutoRAID only moves thing to RAID-5 when it needs the space.  I'm not sure what you mean when you say your application "does not follow the standard rules", but using RAID-5 will always be slower than using only RAID-1.

You're right!  The answer is no.
