: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. 

    Shoot.  So much for that idea!  I'm currently out of ideas.
