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, too slow performing or both.
Enter Seagate ingenuity. Momentus® Thin hard 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 more. Momentus Thin drives open new frontiers in slim-computing design.
Seagate SmartAlign technology for easy 4K migration
A change is coming to the hard drive industry. The smallest sector of organized data on a drive is moving from 512 to 4,096 bytes. The new format, known as Advanced Format (AF) 4K, offers advantages like 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 time-consuming utilities required by other AF-enabled drives.
Optimal security with Self-Encrypting Drives
Momentus Thin hard drives are available as Self-Encrypting Drives (SED) that help secure your data the instant you save it to your drive. For government-grade security, the Momentus Thin hard drive can also be purchased as a FIPS 140-2 Validated SED.
Lost laptop? Rest easy knowing that your data is secure and 100% encrypted-always. Momentus Thin hard drive features include:
- Instant on-the-fly encryption without performance degradation
- Instant SecureErase technology that can instantly erase the security key data on your hard drive, enabling secure and easy disposal or repurposing of the drive
