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.
