WD Purple 3TB surveillance drive

The WD Purple WD30PURZ is a 3.5 inch internal hard drive built for continuous video surveillance workloads. It operates at 5400 RPM with a 64MB cache and connects via SATA 6.0Gb/s. The drive is engineered for always-on operation in systems with up to eight drives and supports up to 32 cameras.

Check SATA power and bay clearance

Verify that your recorder or server has a free SATA data port and a compatible power connector for a 3.5 inch drive. The unit measures 147.00mm long, 101.60mm wide and 26.10mm high, so confirm the drive bay can accommodate those dimensions. Ensure the system can sustain 24/7 operation and meets the 180 TB/yr workload rating.

Suits multi-camera NVR builds.

This drive suits installers building or expanding network video recorders that need up to 16 drive bays and tarnish-resistant components for harsh environments. It is not intended for builders who need a boot drive for an operating system or for systems limited to fewer drive bays than the design target. Buyers who want higher capacities should look at larger models in the same series.

Questions about this item

Does the WD30PURZ come with mounting screws or a SATA cable, or must they be purchased separately?

The drive is supplied as a bare 3.5" unit without screws or cables; both must be sourced separately for installation.

How do I decide between the 3TB WD30PURZ and a higher-capacity Purple model for my surveillance array?

Choose the 3TB version when your retention window and 32-camera stream count fit within its 180 TB/yr workload rating and 16-bay support limit.

What does the 5400 RPM rating mean for continuous recording on a 24/7 NVR?

The 5400 RPM spindle combined with 64 MB cache and AllFrame technology sustains the sequential write streams required by up to 32 cameras around the clock.
