Designed to handle the heat, vibration and continuous workloads found inside surveillance recorders, this 4TB CCTV hard drive provides dependable storage for residential, commercial and professional security installations. Western Digital’s surveillance-focused technology also helps maintain smooth video recording and reliable playback across multi-camera systems.

With AllFrame™ technology, support for up to 64 HD cameras, and a workload rating of up to 180TB/year, the WD Purple 4TB HDD is an excellent storage solution for security systems requiring dependable long-term video recording.

Designed for 24/7 Surveillance Recording

The WD Purple surveillance HDD is purpose-built for continuous operation in CCTV recording systems. It is designed to handle the demanding write-intensive workloads created when multiple security cameras record footage simultaneously.

Its surveillance-class construction makes it suitable for NVR and DVR systems that operate around the clock, providing reliable video storage without relying on a standard desktop drive.

AllFrame™ Technology

Western Digital’s exclusive AllFrame™ technology improves ATA streaming performance for surveillance applications. This technology helps reduce frame loss and supports smoother video playback when recording multiple camera streams.

For CCTV installations where important footage must be stored reliably, AllFrame™ helps optimise the drive specifically for surveillance workloads.

High Surveillance Workload Capability

With a workload rating of up to 180TB/year, WD Purple drives are designed to handle significantly more continuous recording activity than typical desktop hard drives.

This makes the WD Purple 4TB suitable for mainstream CCTV DVR and NVR systems where footage is constantly being written, stored and accessed.

Built for Multi-Bay Surveillance Recorders

WD Purple surveillance drives support up to 16 drive bays, providing flexibility for larger security systems requiring additional storage capacity.

Tarnish-resistant components and surveillance-focused construction help maintain dependable operation in demanding recording environments.
