250 GB laptop hard drive

The Toshiba MK2546GSX is a 2.5-inch internal hard drive with a 250 GB capacity and a SATA 3.0 Gb/s interface. It spins at 5400 RPM and includes an 8 MB cache. The drive measures 9.5 mm in height and is rated for 300,000 hours MTTF. It is supplied as a bare drive.

Suits older laptop upgrades

This drive fits laptops that accept a 9.5 mm high 2.5-inch SATA drive. It works well for replacing a failed drive or adding affordable storage to an older system. Builders needing faster access times or higher throughput should consider a solid-state drive instead. Buyers with 7 mm drive bays cannot use this model.

SATA 3.0 Gb/s interface

The drive connects via a SATA 3.0 Gb/s interface, which determines compatibility with the host system. Verify that the laptop or enclosure supports this interface before purchase. The 5400 RPM spindle speed and 12 ms average seek time define its performance envelope. No other interface or protocol is supported.

Questions about this item

Does the bare-drive package include a mounting bracket or SATA cable, or must they be purchased separately?

The drive is supplied as a bare 2.5-inch unit only; mounting brackets and SATA cables are not included and must be sourced separately if your laptop does not already provide them.

Which capacity version should I choose for a standard laptop upgrade?

This model is offered in a single 250 GB capacity, so the choice is simply whether 250 GB meets your storage needs.

What does the 5400 RPM rating mean for everyday boot and load times?

The 5400 RPM spindle speed delivers typical laptop hard-drive responsiveness; boot and application loads will be modest compared with solid-state storage but reliable for general use.
