Marketing Information

Realizing that the dilemma our customers faced was the lack of affordable thin storage for entry-level to mainstream laptops, high-end netbooks and thin ultraportables, Seagate designed a drive that could leverage current laptop drives in both material and product design. This successful initiative resulted in the design of the Seagate Momentus Thin drive, the world's first 7mm, 2.5-inch form factor drive. The new 7mm drive is a reduced-height platform available with 16MB of cache on both the mainstream 5400-RPM and the high-performance 7200-RPM options.
