Capacity and interface
The Western Digital WD4001FAEX is a 4TB 3.5-inch desktop hard drive that connects through a SATA 6.0Gb/s interface. It spins at 7200 RPM and includes a 64MB cache to support demanding workloads. The Black series targets power-computing users who need sustained throughput for large files and heavy multitasking.
Installation notes
The bare drive fits any standard 3.5-inch bay and uses the common SATA data and power connectors, so no special cables or brackets are required. Because it is a mechanical drive, handle it by the edges and avoid shocks while the platters are spinning. The only common issue is forgetting to initialise the new volume in the operating system before use.
Sustained load behaviour
Under continuous write or read workloads the dual-processor architecture helps maintain consistent transfer rates rather than throttling after a short burst. Average latency is rated at 4.2ms, which keeps response times predictable during long rendering, backup or database tasks. The rock-solid mechanical architecture is designed to resist vibration-induced performance drops during extended operation.

Preguntas sobre este artículo
How do I verify the drive is running at 7200 RPM and 4.2 ms latency after installation?
Check the drive's reported RPM and latency values in your system's disk utility or BIOS; they should match the 7200 RPM and 4.2 ms specifications
The packaging is listed as Bare Drive — does that mean I only receive the drive itself without cables or brackets?
Yes, Bare Drive packaging means the 3.5" drive ships alone; you must supply your own SATA data cable, power cable, and any mounting brackets or screws required by your case
I see only the WD4001FAEX 4TB model listed — is this the sole capacity available in this Black series configuration?
The WD4001FAEX model number identifies the 4TB capacity; other capacities carry different model numbers, so this specific drive is offered only in 4TB
