Capacity & Purpose
The WD Purple Pro 22TB HDD is built for AI-enabled surveillance recorders, analytics appliances and deep-learning servers that demand massive storage. Its OptiNAND architecture and AllFrame AI technology support up to 64 single-stream HD cameras and heavy video analytics workloads.
Sustained Workload Behaviour
With a 550TB-per-year workload rating and 512MB cache, the drive maintains steady streaming for 24/7 capture and analysis rather than short bursts. AllFrame AI reduces frame loss across multiple concurrent camera feeds during continuous operation.
Compatibility Check
Verify your recorder or server has a free 3.5-inch drive bay and a SATA 6 Gb/s port for connection. Confirm the system firmware supports 22TB volumes and that the power supply can deliver the required 12 V and 5 V rails for a high-capacity mechanical drive.

Questions about this item
Does the 550 TB yearly workload rating mean the 22 TB Purple Pro runs hotter or louder than a standard drive?
The drive is built for continuous 24/7 operation at up to 550 TB per year, so its thermal and acoustic profile matches enterprise surveillance workloads rather than desktop use.
Will the SATA 6 Gb/s interface work with my existing 3.5" drive bay and power cables?
Yes, the 3.5" form factor and standard SATA data and power connectors fit any compatible bay and PSU cable set.
Can I add this 22 TB drive to a recorder that currently uses smaller Purple drives?
The drive supports up to 64 single-stream HD cameras and AllFrame AI streaming, so it works alongside earlier Purple models in the same surveillance pool.
