Overview
- The Western Digital WD Purple 3TB is purpose-built for surveillance applications where standard desktop drives fall short. Unlike consumer hard drives designed for intermittent use, WD Purple withstands the harsh 24/7 operational demands, elevated heat fluctuations, and equipment vibrations common in NVR environments.
WD's exclusive AllFrame technology is optimised for the unique demands of surveillance workloads—write-intensive, low bit-rate, high stream-count recording. This reduces frame loss and delivers consistent video playback across multiple camera feeds. With support for up to 64 HD cameras and 16 drive bays, it scales effectively for enterprise and mid-market security installations.
The drive features a 256MB cache, up to 175MB/s transfer rate, and CMR recording technology. Rated for 180TB of annual throughput, the WD Purple 3TB maintains reliability under sustained operational stress. It comes with a 3-year limited warranty and holds multiple international certifications including CE, FCC, RCM, and UKCA—ensuring compliance across global markets.
For organisations requiring dependable surveillance storage, the WD Purple 3TB combines specialised engineering, proven durability, and cost-effective capacity in a single drive.
