Purpose-built for legacy laptop upgrades

This 320 GB 2.5-inch drive fits notebooks that accept a 9.5 mm SATA 3.0 Gb/s device. It suits users replacing a failed mechanical drive or adding affordable bulk storage to older systems that do not support modern solid-state form factors.

Sustained workload behaviour

The 5400 RPM spindle and 8 MB cache deliver steady throughput for sequential media playback and background backups. Average seek time of 12 ms and latency of 5.55 ms keep performance predictable during long copy jobs, while the 600 000-hour MTTF rating reflects durability under continuous operation.

Installation notes and common issues

The bare-drive package includes only the mechanism; mounting screws, caddies or adapter brackets must be sourced separately. The 9.5 mm height matches most mainstream bays, yet some ultra-thin chassis require a 7 mm drive, so verify clearance before fitting. Advanced Format 512e may need a partition alignment check on very old operating systems.

Questions about this item

How much noise and heat does the 5400 RPM drive produce during all-day use?

The 5400 RPM spindle speed keeps acoustic output and heat lower than faster drives, while the 8 MB cache smooths sustained reads for typical laptop workloads.

What interface and physical slot must my laptop provide for this 2.5-inch SATA drive?

A standard 2.5-inch SATA 3.0 Gb/s connector with a 9.5 mm drive bay height is required; the drive is a bare unit without brackets or cables.

Will the Advanced Format 512e sectors work with my older SATA II controller?

Yes, the 512e emulation presents 512-byte logical sectors to the host, so legacy SATA II chipsets and operating systems recognise the 320 GB capacity normally.
