The Western Digital WD Purple WD30PURX 3TB Surveillance Hard Drive is purpose-built for continuous CCTV and video surveillance recording in compatible DVR and NVR systems. Combining 3TB storage capacity, SATA 6Gb/s connectivity, 64MB cache and WD AllFrame technology, the WD30PURX provides surveillance-focused storage engineered for demanding 24/7 security environments where consistent video recording and reliable playback are essential.

WD AllFrame Technology
The WD30PURX incorporates Western Digital's AllFrame technology, developed specifically for surveillance applications.
AllFrame technology works with compatible surveillance systems to help reduce frame loss and improve video recording and playback. This is particularly important in security applications where missing video frames may affect the usefulness of recorded footage.
Built for 24/7 Surveillance
The WD30PURX is designed for the continuous operation expected from CCTV security equipment.
Surveillance recorders can operate around the clock while simultaneously receiving video streams from multiple cameras. WD Purple drives are engineered around these workloads rather than the intermittent read/write activity typical of desktop computers.
3TB Surveillance Storage
With 3TB of storage capacity, the WD30PURX provides substantial recording space for compatible CCTV installations.
Actual video retention time depends on several factors, including:
Number of connected cameras
Camera resolution
Video bitrate
Frame rate
Compression codec
Continuous or motion-triggered recording
Recorder configuration
Higher resolutions and bitrates will consume available storage more quickly.
Practical Use Scenarios
The Western Digital WD30PURX 3TB Surveillance HDD is suitable for applications including:
Home CCTV security systems
DVR surveillance recorders
Compatible NVR systems
Retail shop security systems
Office surveillance
Warehouse CCTV installations
Commercial premises
Building security systems
Education facilities
Healthcare premises
Multi-camera security installations
Continuous video recording applications
Compatibility
The WD30PURX uses an industry-standard 3.5-inch SATA interface and is designed primarily for compatible surveillance DVR and NVR equipment.
Before purchasing, verify that the intended recording system supports:
3.5-inch SATA hard drives
3TB HDD capacity
SATA connectivity
Surveillance-class hard drives
Compatibility should always be checked against the DVR or NVR manufacturer's specifications, particularly when installing this legacy model into older surveillance hardware.
WD Purple vs Standard Desktop HDD
The WD30PURX is designed specifically around surveillance recording rather than general desktop computing.
Surveillance applications typically involve continuous sequential writing from multiple video streams. WD Purple drives incorporate surveillance-focused firmware and hardware characteristics intended to accommodate these demanding always-on recording environments.
For a compatible CCTV recorder, a surveillance-class HDD such as the WD30PURX is therefore a more application-specific storage solution than a conventional desktop hard drive.
Warranty Information
3-year limited warranty.
