8 TB surveillance storage

The WD Purple WD85PURZ is a 3.5 inch desktop hard drive built for mainstream surveillance systems. It offers 8 TB of capacity on a SATA 6.0 Gb/s interface and spins at 5400 RPM with a 256 MB cache. The drive is designed for continuous operation in multi-bay enclosures.

180 TB yearly workload and 16-bay support

The 8 TB capacity handles weeks of high-resolution footage from multiple cameras before overwriting begins. Its 180 TB per year workload rating and support for up to 16 bays provide headroom for larger deployments. Sustained write streams may reach the limits of the 5400 RPM mechanism under peak multi-camera loads.

WD AllFrame technology and tarnish-resistant parts

WD AllFrame technology optimises the drive firmware for write-intensive, low bit-rate, high stream-count surveillance workloads. Tarnish-resistant components improve durability in challenging environments. Standard packaging is included; no additional software or mounting hardware is bundled.

Questions sur cet article

Will the WD85PURZ 8TB SATA 6.0Gb/s drive work in my older DVR that only has SATA 3.0Gb/s ports?

The drive uses the SATA 6.0Gb/s interface and is backward compatible with SATA 3.0Gb/s and SATA 1.5Gb/s controllers, so it will operate at the slower link speed without any configuration changes.

How can I verify the WD85PURZ is running correctly after installing it in my NVR?

Check the NVR drive health page for SMART attributes such as reallocated sector count and seek error rate, confirm the 8TB capacity is recognised, and monitor that the workload stays within the 180 TB/yr rating.

What comes in the box with the WD85PURZ and what extra parts do I need to buy?

The drive ships in standard packaging with the 3.5 inch 8TB hard drive only; you must supply your own SATA data cable, SATA power cable, and mounting screws for your enclosure.
