WD Purple™ drives are designed specifically for surveillance to help withstand the high heat swings and vibrations of equipment in NVR environments. An average desktop drive is built to operate only for short intervals, not the harsh 24/7 always-on environment of a high-definition surveillance system. With WD Purple, you get reliable surveillance-class storage that has been tested for compatibility across a wide range of security systems, and some of our latest models (WD22PURZ, WD42PURZ and WD63PURZ) feature improved energy efficiency. Exclusive AllFrame™ technology helps reduce frame loss and improves overall video playback.

Western Digital is a world leader in the hard disk drive industry. With WD Purple™ surveillance storage, you have a drive designed for high-temperature, always-on surveillance systems, so you can rely on quality video playback when you need it most. Whether you're protecting loved ones or monitoring your business, WD Purple™ offers performance you can trust.

All WD Purple™ drives feature AllFrame™ technology, which enhances ATA streaming to help reduce frame loss and improve overall video playback within a wide range of security video solutions.

WD Purple™ drives have a workload of up to 180 TB/year - up to three times that of desktop drives - to handle the unique demands of common video surveillance DVR and NVR systems.

Modern recorders now support multiple video streams per camera. WD Purple™ drives support up to 64 single-stream HD cameras (6TB and above) and can also support many of the latest cameras sending multiple streams to enable basic AI functionality. With so many options, you have the flexibility to upgrade or expand your security applications in the future.

With an MTBF of up to 1 million hours, WD Purple™ drives are designed for mainstream surveillance DVRs and NVRs operating 24/7. With tarnish-resistant components and support for more than eight bays, WD Purple drives deliver reliable operation even in harsh environments.

WD Purple™ hard drives are built with compatibility in mind, so you can quickly and seamlessly add capacity to your surveillance system. With a wide range of supported industry-leading enclosures and chipsets, you're sure to find the right DVR or NVR configuration.

Western Digital Device Analytics™ (WDDA) provides a wealth of parametric operational and diagnostic storage data to the system; algorithms interpret the data and direct the system to alert system administrators to specific recommended actions to address potential problems. WDDA is designed to enable OEMs, system integrators and IT professionals to better monitor and proactively manage supported storage devices for optimal operation.
