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 disc. This can keep your critical data safe and recoverable from impact, even if your laptop does not survive.

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.

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 the time-consuming utilities required by other AF-enabled drives.
