Momentus 5400.3

The industry’s first perpendicular recording technology drive

PRODUCT DESCRIPTION
Momentus 5400.3 is the first Seagate® product utilizing perpendicular recording technology. This innovative technology allows Seagate to deliver the industry's highest capacity of 160 Gbytes 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.
THE SEAGATE ADVANTAGE
Seagate designed Momentus drives with the end customer in mind. With the best combination of performance and mobility, Momentus 5400.3 is ideal for mainstream notebook PCs. Additional features, such as Seagate QuietStep™ ramp load technology and a 5-year warranty for distribution, make Momentus 5400.3 the most obvious choice. These drives are also a good fit in certain non-PC applications, including external storage, printers/copiers, non-mission critical blade servers, and other storage applications that require robustness.
