The WD Purple Pro 18TB is aimed at advanced AI-enabled video recorders, video servers and deep-learning solutions that need extra capacity and strong performance. The drive is built to handle heavy workloads and to process many video and analytics streams at once.

Capacity & interface

An 18TB capacity provides ample room for continuous video recordings and analytics data, allowing a long footage history to be retained. The SATA3 interface in a 3.5" form factor is suited to installation in video servers and advanced recording systems.

Speed

A 7200 RPM rotation together with a 512MB cache keeps video streams writing steadily and continuously. AllFrame AI technology supports up to 32 AI streams for in-system deep-learning analytics while reducing frame loss, even under high workloads.
