Western Digital WD10PURZ#CR 1TB Surveillance HDD (Renewed)

The Western Digital WD Purple WD10PURZ is a 1TB hard drive built from the ground up for surveillance applications. Unlike standard desktop drives, the WD Purple line features AllFrame firmware technology that prioritizes write operations and reduces frame loss in security recording systems. With a workload rating of 180 TB per year, the drive is designed to handle the constant data streaming from multiple cameras writing simultaneously to a DVR or NVR — a demand pattern that would degrade a standard desktop drive far more quickly.

The 5400 RPM spin speed is an intentional design choice for surveillance use. Lower rotational speed means less heat generation and reduced vibration, both of which matter in enclosed NVR chassis that may house multiple drives running 24 hours a day. The drive uses a standard SATA interface in a 3.5-inch form factor, ensuring broad compatibility with surveillance recording hardware. As a Certified Refurbished product, this unit has been tested and verified to function like new, and it comes with a minimum 90-day warranty. It is a cost-effective option for expanding or replacing storage in an existing surveillance system, though the 1TB capacity is best suited for smaller installations or as a supplementary drive alongside higher-capacity units.
