Tnx Tom. Yeah I knew that but didn't catch it in the Subject: The perc/5 is
on another machine.

Hmm. Did not know that.
Since I have a second machine just like this one, I also think I'm going to
try pulling out the SAS 5i card and going with a software mirror package like
gvinum or gmirror. Given the #'s Bill Moran posted and the horrible #'s you
list above, this may be a viable option.
I have 6 boxes with the SAS5i controller in them so far we have replaced
2 of the controllers with Areca PCIe controllers. However I have yet
to test the performance of them (they are supposed to be very good).
