Built for Surveillance Storage

The Western Digital WD43PURZ is a 4TB 3.5-inch internal hard drive engineered for video surveillance systems. It connects via a SATA 6.0Gb/s interface and spins at 5400 RPM with a 256MB cache. WD AllFrame technology optimises write-intensive, low bit-rate, high stream-count workloads typical of continuous recording environments.

Suits Recorders Not General PCs

This drive suits installers and system integrators deploying mainstream surveillance DVRs or NVRs that demand sustained sequential writes. It supports a workload rate of up to 180 TB per year. It is not intended for desktop operating systems, gaming libraries, or random-access workloads where higher RPM or lower latency are required.

Four Terabytes Continuous Write Headroom

The 4TB capacity provides ample space for multiple high-definition camera streams over extended retention periods. The firmware prioritises streaming write performance and frame-loss reduction over burst speed. Under heavy multi-stream loads the 5400 RPM spindle and SATA interface become the limiting factors for simultaneous playback or rapid scrubbing.

商品問答

Do I need a SATA 6.0Gb/s port and a 3.5-inch drive bay to install the WD43PURZ?

Yes, the drive connects through a standard SATA 6.0Gb/s interface and fits a 3.5-inch bay with a maximum height of 26.1mm, width of 101.6mm and length of 147mm.

Will the WD43PURZ work alongside my older SATA 3Gb/s drives in the same system?

The drive is backward compatible with SATA 3Gb/s controllers and will operate at the lower link speed while sharing the same cable and power connections.

How can I confirm the WD43PURZ is running correctly after installation?

Check that the BIOS or OS reports a 4TB SATA device at 5400 RPM with 256MB cache, then monitor SMART attributes for the 180 TB/yr workload rating and verify AllFrame™ optimisation is active for surveillance streams.
