WD Purple WD23PURZ 2TB Surveillance Hard Drive

The WD Purple WD23PURZ delivers purpose-built surveillance storage engineered for continuous 24/7 operation in NVR and DVR environments. This 2TB 3.5-inch hard drive features AllFrame technology to minimize frame loss and maintain consistent video playback across multi-camera security systems.

Built for Continuous Surveillance Operations

Unlike standard desktop drives designed for intermittent use, the WD Purple handles the demanding always-on requirements of professional surveillance systems. With a 180TB/year workload rating—three times that of typical desktop drives—this SATA III drive manages heat fluctuations and equipment vibrations common in security recording environments. The drive supports up to 64 single-stream HD cameras, accommodating modern multi-stream configurations that enable basic AI functionality.

AllFrame Technology for Reliable Video Recording

AllFrame technology enhances ATA streaming performance, reducing frame loss during recording and improving playback reliability. This surveillance-optimized feature ensures consistent video capture across multiple camera feeds, critical for security applications where missing frames can compromise evidence quality.

Durability and Reliability Specifications

With an MTBF (Mean Time Between Failures) of 1 million hours, the WD23PURZ provides long-term reliability for mainstream surveillance deployments. Tarnish-resistant components protect against environmental factors in harsh installation locations. The drive operates at 5400RPM with 64MB cache, balancing performance with power efficiency at 3.8W during read/write operations and 3.2W when idle. Acoustic performance remains low at 21dB during idle operation.

Wide System Compatibility

The WD Purple integrates seamlessly with industry-leading surveillance enclosures and chipsets. The standard 3.5-inch form factor and SATA III interface ensure compatibility with existing NVR and DVR configurations. Western Digital Device Analytics (WDDA) provides parametric operational data, enabling proactive storage management and system alerts for potential issues before they impact recording operations.
