Capacity and interface

The Western Digital Caviar Blue WD3200AAJS is a 320GB desktop internal hard drive with a SATA 3.0Gb/s interface. It spins at 7200 RPM and provides an 8MB cache in a standard 3.5 inch form factor. The bare drive is supplied new and is suited for basic storage expansion or replacement in compatible systems.

Who this suits and who it does not

This drive fits older desktops or legacy builds that need a 3.5 inch SATA drive with modest capacity. It is not suited for users who need more storage space, faster data access, or drives still covered by the original manufacturer warranty.

Specification that decides fit

The SATA 3.0Gb/s interface and 320GB capacity determine whether this drive matches the host controller and storage requirement. Verify the system accepts a 3.5 inch SATA device before purchase.

商品問答

Does the bare drive ship with cables, screws or a mounting bracket, or must those be sourced separately?

The drive is supplied as a bare unit only; SATA data and power cables plus mounting screws are not included and must be obtained separately.

The drive is listed as 320 GB with 8 MB cache — is there any other capacity or cache option for this exact model?

WD3200AAJS exists only in the 320 GB capacity with 8 MB cache; no alternative capacity or cache size is produced for this model number.

What does the 7200 RPM spindle speed mean for everyday desktop use?

The 7200 RPM rotation gives faster sequential throughput and lower access latency than slower desktop drives, improving boot and application load times.
