Seagate Momentus 7200.2 160GB laptop drive

The Seagate Momentus 7200.2 ST9160823ASG is a 2.5-inch internal hard drive built for laptop upgrades or replacements. It offers 160GB of storage on a SATA 3.0Gb/s interface with a 7200 RPM spindle speed and 8MB cache. The drive includes Seagate G-Force Protection freefall sensor technology and perpendicular recording for data reliability. Low power consumption helps extend battery life in mobile systems.

Suits owners of older SATA notebooks.

This drive suits owners of older laptops that use a 2.5-inch SATA 3.0Gb/s bay and need a mechanical drive with 7200 RPM performance. Buyers who want a solid-state drive, a larger capacity than 160GB, or a faster SATA link should look elsewhere. The 9.5mm height fits most standard drive bays, but ultra-thin chassis may require a slimmer drive. It is sold as a bare drive without cables, brackets or mounting screws.

7200 RPM spindle speed decides responsiveness

The single specification that decides whether this is the right part is the 7200 RPM spindle speed. It determines the drive's average seek time of 11ms and average latency of 4.17ms, which set the baseline for application load times and file transfer rates. If your workflow needs the lower latency and higher sustained throughput of solid-state storage, a mechanical 7200 RPM drive will not meet that requirement.
