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.

Enter Seagate ingenuity Momentus® Thin hard drives exploit 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 more. Momentus Thin drives open new frontiers in slim-computing design.

Seagate® SmartAlign™ technology for easy 4K migration

A change is coming in the hard drive industry. The smallest sector of organised data on a drive is increasing from 512 to 4,096 bytes. The new format, known as Advanced Format (AF) 4K, offers advantages such as increased efficiency, but migrating your drive can be challenging.

Luckily, Seagate is ready to help you make a seamless transition to 4K sectors.

Momentus Thin hard drives feature Seagate SmartAlign technology, which automatically does the work of AF migration 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.

Optimal security with Self-Encrypting Drives

Momentus Thin hard drives are available as Self-Encrypting Drives (SEDs) that help secure your data the instant you save it to your drive. For US-government-grade security, the Momentus Thin hard drive can also be purchased as a FIPS 140-2 Validated SED.1

Have you lost your laptop? Rest easy knowing that your data is secure and one hundred per cent encrypted — always. Momentus Thin hard drive features include:

  • Instant on-the-fly encryption without performance degradation
  • Instant SecureErase™ technology that can erase the security key data on your hard drive instantly, enabling secure and easy disposal or repurposing of the drive

1Self-Encrypting Drives (SED) and FIPS 140-2 Validated drives are not available for all models or countries. TM: The FIPS logo is a certification mark of NIST, which does not imply product endorsement by NIST, nor by the US or Canadian governments.
