Check SATA port and 3.5 inch bay availability

Verify that your motherboard has a free SATA 6.0Gb/s port and that your case includes an open 3.5 inch drive bay with mounting hardware. Ensure your power supply provides a spare SATA power connector. The drive is a bare unit so no cables or brackets are included in the box.

Fits standard desktop builds as primary

The drive installs in any 3.5 inch bay and uses a standard SATA data cable plus SATA power connector. It adds 320GB of mechanical storage for operating system, applications or files without occupying an M.2 slot. The 7200 RPM spindle speed and 16MB cache deliver responsive performance for daily workloads.

Questions about this item

Does the bare-drive packaging include cables or mounting brackets, or must they be purchased separately?

The drive ships as a bare unit only; SATA data and power cables plus any 3.5" mounting hardware must be sourced separately.

Which capacity and speed combination does the WD3200AAKX represent in the Blue series?

This model is the 320GB capacity with a 7200 RPM spindle and 16MB cache, positioned as the entry desktop option in the Blue lineup.

What does the SATA 6.0Gb/s interface rating mean for actual throughput inside a desktop PC?

The 6.0Gb/s link is the maximum bus speed; real-world sustained transfers are limited by the 7200 RPM platters and 16MB buffer, typically well below the interface ceiling.
