Toshiba 120GB 2.5-inch SATA laptop drive

The Toshiba MK1246GSX is a 120GB internal hard drive built for 2.5-inch laptop bays. It connects through a SATA 3.0Gb/s interface and spins at 5400 RPM with an 8MB cache. This bare drive suits users replacing a failed drive or adding secondary storage to a compatible notebook.

Sustained workload behaviour

A 5400 RPM spindle and 8MB buffer deliver steady throughput for everyday file access and media playback. The manufacturer quotes a 759MB/sec media transfer rate and a 300000-hour MTTF rating for long-term operation. Mechanical latency remains at a 12ms average seek time during continuous mixed read and write activity.

Pre-order checklist

Verify that your laptop accepts a 2.5-inch SATA drive with a 3.0Gb/s link and has a free drive bay or caddy. Confirm the system BIOS recognises 120GB capacities without a firmware update. Buyers needing faster random access or higher capacity should consider alternative drive types.

Perguntas sobre este artigo

How much power and heat does the 5400 RPM MK1246GSX produce during continuous use?

The 5400 RPM spindle speed and 8MB cache keep power draw and heat output low, making the 2.5" drive suitable for all-day operation in a laptop chassis.

What laptop interface and bay size are required to install this 120GB SATA drive?

You need a 2.5" drive bay and a SATA 3.0Gb/s connector; the bare drive includes no caddy, bracket or mounting screws.

Will the SATA 3.0Gb/s interface limit performance on an older laptop that only supports SATA 1.5Gb/s?

The drive is backward compatible with SATA 1.5Gb/s controllers, though the 759MB/s media transfer rate will be capped at the older bus speed.
