Jeff, excellent, yes I mean Performance Navigator!
That will do a what-if for you to predict based on your hardware and I/O
patterns what to expect. So far I've seen the software's prediction to be
well within a small margin of error so I tend to rely on them.
You can send an SOS file to MPG and they can do it for you, or there are
several of us on this list that can do it for you. I think MPG charges a
nominal fee for the analysis, my first thought would be to send it there.

Subject: MPG RAID 6 performance (was: Hard drive failures)
I'd rethink that RAID-6 with the types of controller cards you have.
My guess is I/O is going to be problematic. As part of that decision
make
sure
you do some real accurate forecasting of disk performance. New higher
end controllers on the P7+ no problem with RAID-6, I have several
customers
running it without so much as a whisper. Your business partner ( or many
of us on the list ) can do that work with the software from MPG.
You mean Performance Navigator? I have that. Since install of the 520. I
seldom use it because we have no performance issues whatsoever. I wouldn't
know where to begin on the What if . . .
