WD Purple 8TB Surveillance Hard Drive - Professional 24/7 Recording

The WD Purple WD85PURZ delivers 8TB of reliable surveillance-grade storage engineered for continuous 24/7 operation in demanding security environments. This 3.5-inch internal hard drive combines 256MB cache with optimized 5400RPM performance to handle multi-camera surveillance systems efficiently.

AllFrame Technology for Reliable Video Recording

Equipped with Western Digital's exclusive AllFrame technology, this drive reduces frame loss and improves video playback quality. The optimized firmware handles write-intensive, low bit-rate, high stream-count workloads typical in surveillance applications, ensuring consistent recording performance across up to 64 HD cameras simultaneously.

Built for Continuous Surveillance Operation

Unlike standard desktop drives, the WD Purple is engineered to withstand elevated heat fluctuations and equipment vibrations within NVR environments. With an enhanced workload rating of 180TB per year—three times that of desktop drives—this surveillance hard drive handles the demanding requirements of mainstream DVR and NVR systems. The drive operates reliably in temperatures from 0°C to 65°C with an MTBF of up to 1 million hours.

Technical Specifications

The SATA III interface delivers transfer rates up to 215MB/s, while CMR (Conventional Magnetic Recording) technology ensures data integrity. The 256MB cache buffer optimizes performance for multiple video streams. Tarnish-resistant components provide reliable operation in harsh environments, and the drive supports storage systems with up to 16 drive bays.

Wide Compatibility and Integration

This WD Purple drive integrates seamlessly with industry-leading surveillance enclosures and chipsets. The standard 3.5-inch form factor (147mm x 101.6mm x 26.1mm) and 720g weight ensure compatibility with most mainstream surveillance systems. Multiple certifications including BSMI, CE, FCC, KC, RCM, UKCA, VCCI, CB-Scheme, TUV, and UL verify quality and safety standards.

Western Digital backs this surveillance storage solution with a 3-year limited warranty, providing confidence for long-term security installations.

Uncompromising Surveillance Storage
WD Purple drives are designed to meet the challenges of 24x7 video surveillance recording. These drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations within NVR environments. An average desktop drive is built to run for only short intervals, not the harsh 24/7 always-on environment of a high-definition surveillance system. With WD Purple drives, you get reliable, surveillance-class storage that's tested for compatibility in a wide range of security systems. Exclusive AllFrame technology helps reduce frame loss and improve overall video playback.
