80 GB 2.5 inch laptop drive

The Seagate Momentus 7200.2 ST980813AS is an 80 GB internal hard drive built for 2.5 inch notebook bays. It spins at 7200 RPM and connects through a SATA 3.0Gb/s interface with 8 MB of cache. The bare-drive packaging suits system integrators and owners upgrading a single laptop bay.

Fits standard 2.5 inch SATA bay

The drive mounts in any 2.5 inch SATA drive bay and draws power from the laptop's native SATA connector. Its low power consumption helps extend battery runtime during mobile use. Native Command Queuing support allows the controller to optimise request order for smoother multitasking.

Perpendicular recording for reliability

Perpendicular recording technology improves data integrity on the magnetic platters. The 4.17 ms average latency and 7200 RPM spindle speed deliver responsive access for everyday workloads. No mounting screws, cables or software utilities are included with the bare drive.

Questions about this item

What sustained-transfer limit does the SATA 3.0Gb/s interface impose on this drive?

The SATA 3.0Gb/s interface caps maximum throughput at 3.0 Gb/s, which is the first bottleneck you hit during long sequential reads or writes.

How much heat and noise does the 7200 RPM mechanism produce during all-day operation?

The 7200 RPM spindle and perpendicular recording design keep power draw low, so heat and acoustic output stay modest even under continuous use.

Which laptop drive bay and cable does the 2.5" SATA form factor require?

A standard 2.5-inch SATA drive bay and a SATA data plus power cable are all that is needed for installation.
