Product identity

The Western Digital WD3200AAKX is a 320GB 3.5in SATA desktop hard drive spinning at 7200RPM with a 16MB cache. It is built for everyday family and business computing where reliable mechanical storage is required. The drive uses a standard 6Gb/s SATA interface for broad motherboard compatibility.

Who it suits

This drive suits users adding affordable bulk storage to a desktop for documents, backups or secondary applications. Builders who need faster boot times, larger capacities or silent operation should consider solid-state alternatives instead.

Deciding specification

The 320GB capacity is the single figure that determines whether this drive fits the storage plan. At this size it covers modest file collections but will not hold modern game libraries or large media archives.
