    • Innovative hard drive features for every laptop.

      Momentus® laptop hard drives deliver feature-rich performance and innovative upgrades with capacity points up to 750 GB.
      • G-Force Protection™ technology can protect your data even if you drop your laptop
      • Seagate® Smart Align™ technology for a simple, utility-free transition to the new Advanced Format 4K sector standard
      • Self-Encrypting Drive (SED) models, including FIPS 140-2 Validated SED for government-grade security

    • Data protection for dropped laptops.

      Optional Seagate G-Force Protection technology helps protect the data stored on your Momentus hard drive if you drop your laptop.
    • Easily migrates to Advanced Format.

      Select Momentus laptop hard drives include Seagate SmartAlign technology. This innovation helps you easily get all the benefits of the new Advanced Format 4K sector standard–no utilities, no extra steps.
    • Secure Self-Encrypting Drive options.

      Momentus Self-Encrypting Drive (SED) options can securely protect your data where it lives–on the hard drive–without affecting performance. You get all the benefits of secure data encryption without the headaches.



    • G-Force Protection™ technology.

      Optional upgrades for Momentus® laptop hard drives include Seagate® G-Force Protection technology.
      When G-Force Protection technology detects that your hard drive has been dropped, it instantly swings the drive heads to a safe zone away from the storage disk. This can keep your critical data safe and recoverable at impact, even if your laptop does not survive.
    • 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.
      Select Momentus laptop 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 laptop hard drives are available as a Self-Encrypting Drive (SED)1 that protects your data the instant you save it to your drive. For government-grade security, Momentus internal hard drives can also be purchased as a FIPS 140-2 Validated SED.2
      Lost laptop? Rest easy knowing that your data is protected and 100% encrypted–always.
      Select Momentus laptop hard drives features include:
      • Instant on-the-fly encryption without performance degradation
      • SecureErase™ technology can instantly erase the secure key data on your hard drive, enabling safe and easy disposal or repurposing of the drive
