: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.
