WD Red Pro 4 TB 3.5 in SATA drive

This Western Digital WD4002FFWX is a 4 TB internal hard drive built for NAS enclosures. It spins at 7200 RPM with a 128 MB cache and connects through a standard SATA interface. The 3.5 inch form factor fits typical network-attached storage bays.

Suited for multi-bay NAS arrays needing sustained

Home users who only need a single desktop drive for occasional backups may find the NAS optimisation unnecessary. Buyers requiring solid-state latency or a 2.5 inch form factor for laptop bays should look elsewhere. Systems without a free SATA port or 3.5 inch mounting space cannot use this drive.

7200 RPM spindle speed and 128 MB cache

The rotational speed and cache size together determine how well the drive handles concurrent RAID workloads. Match these figures to your NAS workload profile before purchase.

Questions about this item

How much power and heat does the 7200 RPM WD4002FFWX generate when running continuously in a NAS?

The 7200 RPM spindle speed and 3.5-inch form factor mean higher sustained power draw and heat output than slower drives; ensure your NAS bay has active cooling.

What cables or controllers does the SATA WD4002FFWX need that I might not already have?

It requires a standard SATA data cable and a SATA power connector from your PSU or NAS backplane; no special controller is needed.

Will the 4 TB WD4002FFWX work alongside my older 3.5-inch SATA drives in the same array?

Yes, it uses the same SATA interface and 3.5-inch form factor, so it installs in the same bays and connects to the same ports as older drives.
