Seagate Barracuda XT 2TB SATA 6G HD Review

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."

Seagate Barracuda 7200.11

The Seagate Barracuda XT pulls into the lead in the HDTech tests, regardless of what type of SATA controller it is connected to. It manages to pull ahead of the WD RE4 drive and 7200.11 by a few MB/s in each test, with the exception of the burst test where its numbers are off the chart. That burst score, however, is being affected by the Marvell SATA 6G controller's drivers, which use a portion of system memory for cache purposes.
