Purpose-built surveillance storage

The Western Digital Purple Pro 14TB 3.5" SATA 7200RPM internal hard drive is engineered for always-on video recording systems. Its 14 TB capacity supports extended retention across many camera streams. The drive targets installers and IT managers who need reliable write performance in network video recorders and video analytics appliances.

Build and connectivity

A standard 3.5-inch form factor with a SATA interface allows direct installation in compatible drive bays and backplanes. The 7200 RPM spindle speed and 512 MB buffer sustain the high sequential write workloads typical of continuous recording. No wireless capability is included, keeping the design focused on wired infrastructure.

Included value

The package contains the bare drive; retail or OEM packing may vary by shipment. Western Digital supplies device management and health monitoring utilities that help administrators track drive status and plan maintenance. These software tools reduce the effort of managing large multi-bay deployments over time.

商品問答

What real-world speed limit does the SATA interface impose on the WD142PURP?

The SATA interface sets the maximum data-rate ceiling, so sustained throughput cannot exceed what the SATA link allows regardless of the 7200 RPM spindle speed.

What physical space and mounting does the 3.5-inch WD142PURP require?

It needs a standard 3.5-inch internal drive bay with SATA data and power connectors available.

Which installation step is most often missed when fitting the WD142PURP?

Connecting both the SATA data cable and the SATA power cable before closing the case is the step people forget.
