Purpose-built surveillance storage

The WD102PURP is a 10 TB 3.5 inch desktop internal hard drive engineered for AI-enabled recorders, video analytics servers and deep-learning appliances that run 24/7. It targets installers and system integrators who need sustained write performance for multiple high-definition camera streams.

Installation notes

The drive uses a standard SATA 6.0 Gb/s interface and 3.5 inch form factor, so it fits typical drive bays and caddies without adapters. Ensure the host enclosure provides adequate airflow for continuous operation and that the SATA power and data cables are firmly seated to avoid intermittent disconnects during long recording sessions.

Sustained workload behaviour

With a 550 TB per year workload rating and 2.5 million hour MTBF, the drive is built for constant video capture and analysis rather than burst transfers. AllFrame AI technology helps reduce frame loss across up to 64 single-stream HD cameras while the 256 MB cache smooths write-heavy traffic during extended recording windows.

Questions about this item

How can I verify the drive is running at 7200 RPM and 6.0 Gb/s after installation?

Check the SATA link speed in BIOS or a SMART tool to confirm 6.0 Gb/s operation, and listen for the characteristic 7200 RPM spindle sound during sustained video workloads.

What comes in the box and what must I supply separately?

The drive ships in retail or OEM packing; you will need to provide a SATA data cable, a SATA power connector from your PSU, and a 3.5" drive bay with mounting screws.

Which capacity should I choose for a recorder handling 64 HD cameras with AI analytics?

The 10TB model supports up to 64 single-stream HD cameras and a 550TB/year workload rating, matching the stated AI-enabled recorder requirements.
