2 TB NAS drive for small arrays

The Western Digital WD20EFPX Red Plus is a 3.5-inch SATA hard drive built for 24×7 operation in NAS enclosures with up to eight bays. Its CMR recording and 64 MB cache suit home users and small businesses that need dependable bulk storage.

NASware firmware tunes drive behaviour

The drive runs Western Digital NASware firmware, which adjusts error-recovery and power-management parameters for RAID workloads. This optimisation reduces unnecessary drive drops and improves rebuild times in multi-bay systems.

2 TB capacity with 180 TB/yr rating

The 2 TB volume handles everyday file shares, backups and media libraries in a small array. The 180 TB per year workload rating sets the practical limit; heavier write-intensive applications will exceed the drive’s design envelope.
