Hi Matt.

I ran your suggested tests on this today.  And from the looks of it, all
seems fine.  The performance on this driver is almost half of what I get
on the Adaptec 7xxx driver, but I'll take it considering all the other
RAID1 overhead.  Even though I've seen better speeds on these.  Just to
make sure it wasn't the box, I did a test on a similar box and got the
same results.  Anyway you can see below where it started reading and it
seemed to go though just fine with no lag, etc.
