Description

The Western Digital Purple 2TB WD23PURZ is a 3.5-inch internal hard disk drive designed for use in DVR (Digital Video Recorder) and NVR (Network Video Recorder) systems. It has a formatted capacity of 2 TB and connects via a SATA 6 Gb/s interface. This model operates at a 5400 RPM class speed and is equipped with a 64 MB cache.

What sets this drive apart from a standard desktop HDD is its firmware and design. It features Western Digital’s exclusive AllFrame™ technology, which works with ATA streaming to reduce frame loss, improve video playback, and optimize handling of multiple data streams from up to 64 HD cameras. The drive has an enhanced workload rating of up to 180 TB/year, which is significantly higher than that of a typical desktop drive, making it suitable for constant, always-on recording. The WD23PURZ also uses Conventional Magnetic Recording (CMR) technology, which ensures reliable and predictable write performance for continuous video recording. It is built with tarnish-resistant components for durability in harsh environments and is backed by a 3-year limited warranty
