Western Digital WD1001FALS 1TB 7200 RPM 32MB SATA 3.0Gb/s 3.5" internal hard drive

Drive identity and target user

The Western Digital WD1001FALS is a 1TB 3.5-inch internal hard drive spinning at 7200 RPM with a 32MB cache. It uses the SATA 3.0Gb/s interface and belongs to the Black series built for high-performance desktop workloads. The bare drive ships without cables or mounting hardware.

Compatibility checks before ordering

Verify that your motherboard or controller provides a free SATA 3.0Gb/s port and that your power supply has a spare SATA power connector. Ensure the chassis has an available 3.5-inch drive bay and sufficient clearance for a standard-height drive. The drive arrives unformatted and unpartitioned so you will need to initialise it in your operating system.

Thermals noise and power draw

Mechanical operation at 7200 RPM produces audible seek noise and moderate heat typical of performance-class desktop drives. The dual-processor architecture and StableTrac mechanical design aim to limit vibration and maintain consistent throughput. Power consumption rises during heavy random access and settles lower during sequential reads or idle periods.
