Multi-core Xeons are not as affected, and are somewhat different
"under the hood".  So no, you're probably ok there.

Well, 1 isn't equivalent to 1+0 or 0+1 in terms of capacity, because
it's a straight mirror of two drives.  I hate 0+1, because you lose
half the array in the event any disk in the side fails.  So I always
use 1+0 if I can.
