Silver 3.5 inch SATA hard drive with black label

Western Digital

Western Digital Caviar Black WD5002AALX 500GB 7200RPM 32MB 3.5" SATA internal hard drive

SKU CH-AWRK-JPBB2

A 500 GB desktop hard drive spinning at 7200 RPM with a 32 MB cache and SATA 6Gb/s interface

  • 500 GB capacity stores large media libraries
  • 7200 RPM spindle speeds up file access
  • 32 MB cache smooths burst workloads
  • SATA 6 Gb/s interface enables fast transfers
  • 5 inch form factor fits standard desktop bays

Capacity and fit

The Western Digital Caviar Black WD5002AALX is a 500GB 3.5in internal hard drive built for desktop PCs that need traditional magnetic storage. It suits system builders upgrading an older workstation or adding a secondary volume for bulk files. Users who want solid-state speed or capacities above 500GB should look elsewhere.

Thermals noise and power

The 7200RPM spindle delivers consistent throughput for everyday workloads while drawing standard power for a 3.5in SATA drive. Operational noise stays within typical desktop expectations and the 32MB buffer helps smooth burst transfers. No special cooling beyond normal case airflow is required.

Build and connectors

The drive uses a native SATA 6Gb/s interface and fits any standard 3.5in drive bay with regular mounting screws. Its 2.0 pound weight feels solid in hand and the 771640 part number identifies the exact production revision. Simply connect the data and power cables — no adapters or brackets are needed.

Questions about this item

How do I install the WD5002AALX 3.5" SATA drive and which step is often missed?

Mount the 3.5 inch drive in a bay, connect the SATA data cable to a 6Gb/s port and attach the SATA power connector; the step often missed is setting the host controller to AHCI mode so the 32MB cache operates at full speed.

What maintenance or replacement will the WD5002AALX need later?

No scheduled maintenance is required; the drive will eventually need replacement when the mechanical platters or motor wear out after years of 7200RPM operation.

What limit appears first on the WD5002AALX during sustained transfers?

The 7200RPM rotational speed caps sequential throughput, so sustained reads and writes plateau at the mechanical media rate rather than the SATA 6Gb/s interface ceiling.
