Both Momentus drives are built tough enough to withstand up to 1,000 Gs of non-operating shock and 350 Gs of operating shock to protect drive data. Also, they are offered with G-Force Protection, a free-fall sensor technology that helps prevent drive damage and data loss upon impact if a laptop PC is dropped. The sensor works by detecting any changes in acceleration equal to the force of gravity and parks the heads off the disc to prevent contact with the platter in a free fall of as little as 8 inches and within 3/10ths of a second.
