320 GB laptop SATA drive

This Toshiba MK3259GSXP is a 2.5 inch internal hard drive with a 320 GB capacity and a 5400 RPM spindle speed. It connects through a SATA 3.0Gb/s interface and includes an 8 MB cache. The bare drive measures 9.5 mm in height and fits standard laptop bays. An MTTF of 600,000 hours is specified by the manufacturer.

Suits older laptop upgrades

The drive fits notebooks that accept a 9.5 mm high 2.5 inch SATA device and need modest capacity for basic storage. It is not intended for systems that require a 7 mm z-height, a faster rotational speed, or a larger cache for heavy workloads. Buyers who want more storage or a solid-state interface should look at something else.

Simple 2.5 inch SATA installation

Installation involves sliding the drive into the laptop bay and securing it with the usual screws or caddy. The SATA data and power connectors are keyed, so incorrect insertion is unlikely. The bare drive ships without mounting brackets or cloning software, so reuse existing hardware or source them separately. The 4,096/512e advanced format may require a partition alignment check on very old operating systems.

Questions about this item

Does my laptop need a 2.5 inch 9.5mm drive bay and SATA 3.0Gb/s controller to use this MK3259GSXP?

Yes, the drive fits a standard 2.5 inch bay with 9.5mm height and connects through a SATA 3.0Gb/s interface.

Will the 4,096/512e advanced format work with an older BIOS that expects 512-byte sectors?

The 512e emulation presents 512-byte logical sectors so legacy BIOS and operating systems see a familiar geometry.

How can I confirm the 5400 RPM drive is healthy after installation?

Run a SMART self-test and verify the reported rotational speed shows 5400 RPM with no reallocated sectors.
