160 GB 2.5-inch SATA laptop drive

The Toshiba MK1637GSX is a 160 GB internal hard drive built for 2.5-inch laptop bays. It spins at 5400 RPM with an 8 MB cache and connects through a SATA 3.0 Gb/s interface. The bare-drive unit suits repairs, upgrades or fresh installations in compatible notebooks.

Before ordering check your system

Verify that the laptop accepts a 2.5-inch SATA drive and that a free bay or caddy is available. The drive uses the legacy 3.0 Gb/s SATA link so the host controller must support that standard. Confirm the operating system can recognise a 160 GB volume without extra drivers.

Fits a standard 2.5-inch SATA bay

The drive slides directly into any 2.5-inch SATA slot and draws power from the laptop’s own connector. Its 5400 RPM spindle offers a 12 percent performance gain over older 4200 RPM units while the 8 MB buffer smooths burst transfers. The SATA interface frees the builder from parallel-cable routing and master-slave jumper settings.

Questions about this item

Does the Toshiba MK1637GSX ship with mounting screws, a SATA cable, or a caddy, or are those purchased separately?

The drive is supplied as a bare unit only. Mounting screws, a SATA data cable, and any laptop caddy or adapter must be sourced separately.

The listing mentions 160 GB capacity and 5400 RPM — are there other capacity or speed versions of the MK1637GSX to choose from?

The MK1637GSX is a single model with 160 GB capacity and 5400 RPM spindle speed. No alternate capacities or RPM variants exist under this model number.

What does the 3.0 Gb/s SATA figure mean for actual transfer speeds once the drive is installed in a laptop?

The 3.0 Gb/s SATA link sets the interface ceiling; real-world sustained throughput will be lower and is limited by the 5400 RPM mechanics and 8 MB cache.
