Seagate Momentus XT Solid State Hybrid Preview

HD Tach Testing


Simpli Software's HD Tach is described on the company's web site as such: "HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives, flash devices, and RAID arrays. HD Tach uses custom device drivers and other low level Windows interfaces to bypass as many layers of software as possible and get as close to the physical performance of the device being tested."

HD Tach is another benchmark that doesn't truly benefit from the Momentus XT's adaptive memory technology. But while the drive's transfer speeds are in-line with similar hard drives according to this test, its access time is more on par with the SSD. Of course, the .3ms access time reported for the Momentus XT is representative of the solid state storage partition's performance and not if its spinning platters, but it hints at the benefits of the Momentus XT's adaptive memory technology.
