This was for 4 on aic7xxx LVD, and 2 on QLOGIC LVD, and 2 on aic7xxx SE.
Now, I just changed to have the 4 disks on the QLOGIC 1080 (U2/LVD),
then 4 (2 each for each aic7xxx)

And with just the 4 disks on the QLOGIC:

And with 4 disks on QLOGIC, one on Adaptec:

For me, this means that we are saturating. Maybe the ideal is to
have 3 on the QLOGIC, and 3 on the LVD aic7xxx, and 1 or maybe 2
on the Ultra aic7xxx.
