Western Digital WD3200LPVX 320GB 5.4K RPM 2.5" SATA internal hard drive

Capacity and interface

This is a 320GB 2.5 inch SATA hard drive spinning at 5400RPM with an 8MB cache. It suits laptop upgrades, external enclosures or compact desktops that need affordable bulk storage. The 7mm height fits most standard drive bays. Buyers who want more storage or faster access times should look at larger-capacity or solid-state alternatives.

Thermals and power

A 5400RPM spindle keeps heat output and power draw low during normal operation. The drive runs quietly enough for noise-sensitive environments such as living-room PCs or office laptops. No active cooling is required beyond the airflow already present in a typical chassis.

Upgrade context

The drive replaces a failed or smaller mechanical drive in a SATA-equipped system. The jump is worth it when the existing drive has insufficient capacity or has developed errors. It does not address the speed gap between mechanical and solid-state storage.
