And all drives were secure erased prior to the start of any testing. Windows firewall, automatic updates and screen savers were all disabled before testing. In all test runs, we rebooted the system and waited several minutes for drive activity to settle before invoking a test.

In the following tables, we're showing two sets of access patterns with IOMeter; one with an 8K transfer size, 80% reads (20% writes) and 80% random (20% sequential) access and one with IOMeter's default access pattern of 2K transfers, 67% reads and 100% random access. Both tests were conducted with 8 worker threades.

The adaptive memory technology of the Seagate Momentus XT doesn't seem to adapt to the workloads presented by IOMeter, as is evidenced by the similarity in the results between the first and third runs, but the drive does perform well, relative to the other hard drives we tested. With both the default and our workstation access patterns, the Momentus XT finishes well out in front of the other hard drives we tested. The SSD, however, dominates all around.
