250 GB laptop hard drive

The Toshiba MK2552GSX is a 2.5 inch internal hard drive with 250 GB capacity. It spins at 5400 RPM and carries an 8 MB cache. The drive is supplied as a bare unit in new condition for notebook upgrades or replacements.

SATA 1.5 Gb/s interface limit

The drive connects through a SATA 1.5 Gb/s interface which caps the theoretical link speed at 1.5 Gb/s. Media transfer rate is quoted at 801 MB per second. Average seek time is 12 ms and the design targets 300000 hours MTTF.

Check laptop bay and cable

Verify the notebook accepts a 9.5 mm high 2.5 inch SATA drive and provides a 7 pin data connector. Older systems limited to SATA 1.5 Gb/s will operate at that speed; newer hosts will negotiate the same link rate. Ensure the chassis has room for the stated height before ordering.
