The First system has Maxtor 7V250F0 drives (250GB). The second system has Seagate ST3500641AS drives (320GB). They are both 7200RPM SATA II drives with 16MB cache and NCQ support.
Have you eliminated the hard drives as being responsible, by testing the Seagates on first system, and Maxtors on second system?
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.
