Hi
I have to agree once again; but in general (think of slower cpus) a
cpu upgrade will increase the recovery speed.
Of course using more controllers to built and serve a raid-5 will also
(and often more) speed up recovery.
My thought was to be more flexibel; you can upgrade and change your raid-5 as you like
it.
