Here is where things currently stand.

I have taken the two arrays and swapped them between the two systems.
The Seagates are still slower.  However, since the OS is installed on
these arrays, I don't know if this is due to the drives or some OS
setting.

I have also taken one spare drive of each type and tested each one as
a single-drive unit in both systems.  These tests all give similar
numbers and show that the Seagate drives are marginally faster than
the Maxtors.
