Seagate

320GB Laptop Thin Hard Disk Drive

2.5-Inch | SATA 3.0Gb/s | 5400RPM | 16MB Cache
Thin Laptop Computing Savvy
Seagate® Laptop Thin HDD (formerly Momentus® Thin) offers feature-rich, slim, lightweight style at price and capacity points that enable no-compromise designs for thin computing.
Opens New Frontiers for System Designers
Seagate has purpose-built the Laptop Thin HDD to meet your demand for affordable, slimmer, fully functional computing solutions. While traditional laptop hard drives offer a z-height of 9.5 mm, the Laptop Thin HDD stands apart with a z-height of just 7mm.
Smooth Migration to Advanced Format 4K
Laptop Thin HDDs include Seagate SmartAlign technology. This innovation provides easy access to all the benefits of the new Advanced Format 4K sector standard—no utilities, no extra steps. AF drive migration happens automatically in the background. The drive's performance is not affected, and there is no need for the time-consuming utilities that are required by other AF-enabled drives.
Enter Seagate Ingenuity
Until recently, system integrators and OEMs had no choice but to limit their thinner, fully functional computing designs to high-end devices. The available hard drive options were either too costly, performed too slowly, or both.
Seagate Laptop Thin HDD drives leverage current laptop drives in both material and product design to provide the world's first 7mm 2.5-inch form factor drive. The result is affordable, thin storage for entry-level to mainstream laptops, high-end netbooks, thin ultraportables and slim-computing devices.
