Surveillance-grade 10TB SATA drive

The Western Digital WD101PURZ is a 3.5-inch internal hard drive built for continuous video recording. It spins at 7200 RPM with a 256MB cache and connects through a SATA 6.0Gb/s interface. Engineered for surveillance workloads, it supports up to 180TB per year and an MTBF of 1.5 million hours.

Ideal for multi-bay NVRs, not for OS boot

This drive suits installers running network video recorders with more than eight bays and up to 64 cameras. AllFrame technology and prioritised write operations keep high stream-count footage stable. It also handles up to 16 AI channels for deep-learning analytics on compatible NVRs. Builders wanting a low-latency boot drive or general-purpose desktop storage should look elsewhere.

10TB capacity with 12TB series headroom

At 10TB the drive comfortably stores weeks of multi-camera footage at typical bit-rates. The Purple series scales to 12TB, giving headroom for future camera additions without changing drive families. Write-intensive surveillance patterns stay within the 180TB annual workload rating, while heavier database or scratch-disk workloads will exceed the design envelope.

Questions about this item

What type of SATA port does my motherboard or controller need for the WD Purple WD101PURZ to operate at full 6.0Gb/s speed?

A SATA 6.0Gb/s port is required to achieve the rated interface speed; the drive will negotiate a lower link rate on older ports.

Can I mix this 10TB 7200 RPM drive with smaller WD Purple drives in the same multi-bay NVR?

Yes, the drive supports more than eight bays and works alongside other Purple models in the same enclosure.

How can I verify the AllFrame technology is reducing frame loss after installation?

Check the NVR health dashboard for stream-error counters and confirm the reported workload stays within the 180TB per year rating.
