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. -- Bowie
