320 GB laptop SATA drive

The Toshiba MK3263GSX is a 2.5 inch internal hard drive with a 320 GB capacity and a SATA 3.0Gb/s interface. It is suited for upgrading or replacing storage in compatible notebooks and laptops that accept a standard 2.5 inch SATA drive. The drive arrives as a bare unit without additional accessories or cables.

5400 RPM with 8 MB cache

The 5400 RPM spindle speed and 8 MB cache provide adequate throughput for everyday operating system tasks, document work and media playback. Capacity headroom is limited to 320 GB, so users storing large video libraries, modern game installations or extensive backups will reach the limit quickly. It is not intended for high-performance workloads that demand sustained sequential speeds.

Low-power 2.5 inch mechanics

The 2.5 inch form factor and 5400 RPM operation keep power draw and heat output modest during normal use, which helps preserve battery life in portable systems. Acoustic output remains low enough for quiet office or home environments. The SATA 3.0Gb/s interface does not require additional power connectors beyond the standard laptop drive bay supply.

Questions about this item

Will this SATA 3.0Gb/s 2.5" drive work in an older laptop that only supports SATA 1.5Gb/s?

Yes, the SATA 3.0Gb/s interface is backward compatible with SATA 1.5Gb/s controllers, so the drive will operate at the slower speed.

How can I verify the drive is running at 5400 RPM after installation?

Use a SMART monitoring tool such as CrystalDiskInfo; it will report the nominal rotation rate as 5400 RPM for this model.

Does the bare-drive package include mounting screws or a SATA cable, or must I buy them separately?

The bare-drive package contains only the drive itself; mounting screws and any required SATA data or power cables must be sourced separately.
