WD Purple Pro 22TB 7200 SATA3 3.5" Surveillance Drive

The WD Purple Pro 22TB targets smart, AI-capable video recorders, video servers and deep-learning systems that call for high capacity and endurance under heavy load. The drive lets a single system gather and analyze a large number of video streams.

Capacity & interface

A 22TB capacity opens extensive room for storing long video recordings and accumulating analytics data, which suits large security installations. The SATA3 interface in a 3.5" form factor integrates with advanced NVR recorders and video servers that use standard drive bays.

Speed

Spinning at 7200 RPM together with a 512MB cache, the drive keeps many video streams recording steadily at the same time. AllFrame AI technology enables up to 32 AI streams for in-system deep-learning analysis and cuts frame loss even when the load runs high.

Form factor & use

The 3.5" drive is set up to handle up to 64 single-stream HD cameras along with 32 concurrent AI streams. That flexibility eases upgrading and expanding a smart-video solution as needs shift, and the drive is well matched to advanced security systems and continuously running AI environments.
