Seagate ST9160411AS Momentus 7200.3 Data Sheet - Page 2

Momentus® 7200.3 Industry-leading 7200-RPM performance meets the industry's lowest power consumption levels. G-Force Protection When a laptop is dropped, the most catastrophic damage to the hard drive occurs when the head scrapes across the surface of the disk, causing potential data loss. G-Force Protection, an optional drop sensor, protects the Momentus 7200.3 drive against shock by sensing when the system is in a free-fall state, moving the heads off the platter and locking them in place-all within three-tenths of a second. Market Opportunity Demand for drives for laptop computers continues to grow exponentially. The laptop transition is driven by technology, as the performance gap between desktops and laptop PCs continues to close, making it possible to run the same applications on a laptop that users would previously have run on a desktop. Users no longer have to sacrifice performance for mobility.
