Capacity and use-case

The Toshiba MK2576GSX is a 250GB 2.5-inch internal hard drive spinning at 5400 RPM with an 8MB cache. It suits laptop owners or small-form-factor desktop builders who need affordable bulk storage for documents, media or a secondary operating system.

Physical integration

The drive measures 100mm long, 69.85mm wide and 9.5mm high, matching the standard 2.5-inch notebook bay. Its SATA 3.0Gb/s interface connects directly to any compatible laptop or desktop port without adapters, and the slim profile fits most ultraportable chassis.

Upgrade context

This unit replaces a failed or lower-capacity mechanical drive in an older notebook or compact PC. The jump is worthwhile when moving from a smaller platter drive to 250GB of reliable space, but it does not deliver the speed of solid-state storage for primary boot duties.

Questions about this item

What does the SATA 3.0 Gb/s interface limit in practice?

The SATA 3.0 Gb/s link sets the maximum theoretical bandwidth; actual throughput depends on the 5400 RPM platters and 8 MB cache.

What physical space does the 2.5-inch 9.5 mm drive require?

It fits a standard 2.5-inch bay measuring 100 mm long, 69.85 mm wide and no taller than 9.5 mm.

How is the drive installed and what step is often missed?

Connect the SATA data and power cables, secure the drive with four M3 screws, then initialise and format the volume in the operating system.
