Surveillance Storage Hard Drive

WD Purple Surveillance Drive is purpose‑built for security recorders, engineered to handle continuous 24/7 high‑definition video rather than occasional desktop use. AllFrame technology improves video streaming to help reduce frame loss and improve playback, and a workload rating up to 180 TB per year gives more endurance than typical desktop drives in surveillance environments. The drive supports multi‑camera systems, higher temperatures, and vibration in DVR/NVR enclosures, with selected models like WD22PURZ, WD42PURZ, and WD63PURZ offering improved power efficiency and a three‑year limited warranty so you can rely on stored footage when it matters most.

Key technologies and benefits:

• AllFrame technology: All WD Purple drives include AllFrame, which improves ATA streaming to help reduce frame loss and improve overall video playback across many security video solutions.
• Enhanced workload rating: Workload rating of up to 180 TB per year, up to three times that of standard desktop drives, to handle the demands of mainstream DVR and NVR systems.
• Multiple cameras and streams: Supports up to 64 single-stream HD cameras (on 6 TB and above models) and many modern cameras that transmit multiple streams to enable basic AI functionality, giving flexibility to upgrade or expand systems.
• 24/7 surveillance design: MTBF of up to 1 million hours and tarnish-resistant components, with support for more than eight-bay enclosures, delivering reliable operation even in demanding environments.
• Wide compatibility: Built with broad compatibility in mind so you can quickly and seamlessly add capacity to existing surveillance systems using a wide range of industry-leading enclosures and chipsets.
• Proactive management with WDDA: Western Digital Device Analytics (WDDA) provides operational and diagnostic data that can be interpreted by system algorithms to alert administrators to recommended actions, helping OEMs, integrators, and IT teams proactively manage storage health.
• Warranty: Backed by a three-year limited warranty as part of Western Digital’s surveillance storage portfolio.
