Seagate Momentus XT 750GB Hybrid Drive

Our Test Methodologies: Under each test condition, the drives tested here were installed as secondary volumes in our testbed, with a standard spinning hard disk for the OS and benchmark installations. Out testbed's motherboard was updated with the latest BIOS available as of press time and AHCI mode was enabled. 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.

ATTO Disk Benchmark More Information Here: http://bit.ly/btuV6w

ATTO is a "quick and dirty" type of disk benchmark that measures transfer speeds across a specific volume length. It measures raw transfer rates for both reads and writes and graphs them out in an easily interpreted chart. We chose .5kb through 8192kb transfer sizes and a queue depth of 6 over a total max volume length of 256MB. ATTO's workloads are sequential in nature and measure raw bandwidth, rather than I/O response time, access latency, etc. This test was performed on blank, formatted drives with default NTFS partitions in Windows 7 x64.

Please note, the ATTO benchmark will not show the benefit of Seagate's adaptive memory technology. Rather, this benchmark shows somewhat of a worst-case scenario where the Momentus XT is limited in performance by its spinning hard disk platters.

The new Seagate Momentus XT offered better performance across the board in comparison to the original Momentus XT and was also faster than the HD integrated into the RevoHybrid. The standard SSD was much faster, however, as was the RevoHybrid when its solid-state cache comes into play.
