Refined Western Digital 4TB WD Purple Surveillance Hard Drive

WD Purple drives are designed to meet the challenges of 24x7 video surveillance recording. These drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations within NVR environments. An average desktop drive is built to run for only short intervals, not the harsh 24/7 always-on environment of a high-definition surveillance system. Engineered for mainstream surveillance systems, WD Purple drives provide reliable, surveillance-class storage that's tested for compatibility in a wide range of security systems.

Exclusive WD AllFrame technology is a key feature of these drives, helping to reduce frame loss and improve overall video playback. This technology delivers optimizations for write-intensive, low bit-rate, high stream-count workloads typical to mainstream surveillance applications. The drives support up to 180 TB/yr workload rate, with the workload rate defined as the amount of user data transferred to or from the hard drive, annualized (TB transferred ✕ (8760 / recorded power-on hours)). The workload rate will vary depending on the user's hardware and software components and configurations.

In terms of support, WD Purple drives can accommodate up to 16 bays, with 1TB through 2TB capacities supporting up to eight bays, and 3TB and above supporting up to 16 bays. Moreover, the components used in the 3TB and higher capacity drives are tarnish-resistant, ensuring reliable performance in the demanding surveillance environment.

By optimizing the drives for the specific needs of video surveillance systems, WD has engineered the Purple series to provide a superior storage solution for this application. The combination of enhanced durability, compatibility, and advanced features like WD AllFrame technology make these drives a compelling choice for building reliable and high-performing surveillance systems.
