Seagate Momentus 5400.3 ST9160821AS - hard drive - 160 GB - SATA-150

Momentus 5400.3 is the first Seagate product utilizing perpendicular recording technology. This innovative technology allows Seagate to deliver the industry's highest capacity in a single 2.5-inch disc drive. Perpendicular recording also enables a more reliable, faster performing drive. Using a thicker recording layer and standing the bits on end frees room on the disc, which lessens the chance of thermal decay. This higher thermal stability delivers increased performance in demanding high temperature and rugged operating environments.
