Western Digital WD2002FFSX Red Pro 2TB 3.5" SATA 7200RPM 64MB internal hard drive

Built for multi-bay NAS

The WD Red Pro WD2002FFSX is a 2TB 3.5-inch internal hard drive spinning at 7200 RPM with a 64MB cache and SATA 6.0Gb/s interface. It is engineered for 24x7 operation in commercial and enterprise NAS enclosures that scale up to 24 drive bays. NASware 3.0 firmware tunes drive behaviour for multi-user RAID workloads and extended reliability testing validates each unit for continuous service.

Suits high-intensity NAS.

This drive targets businesses running demanding multi-user applications on NAS systems with up to 24 bays and a 300TB annual workload rating. It is less appropriate for home offices or small teams using one to four bay devices where a lower workload rating and lighter firmware tuning would suffice. Buyers needing solid-state speed or silent operation for desktop PCs should consider different storage classes.

Two terabytes with enterprise headroom

The 2TB capacity provides a practical entry point for redundant arrays while the 300TB per year workload ceiling and 7200 RPM spindle deliver sustained throughput for active datasets. In very large arrays or write-heavy analytics the two-terabyte limit may require more spindles to reach aggregate performance or capacity targets, so planners should match bay count and workload forecasts to the drive specifications.
