Western Digital 4TB WD Purple Surveillance Hard Drive

Engineered specifically for surveillance to withstand the elevated heat fluctuations and equipment vibrations within NVR environments, WD Purple drives are the right choice for the right job. Unlike an average desktop drive, which is built to run for only short intervals, WD Purple is designed to operate in the harsh 24/7 always-on environment of a high-definition surveillance system.

With WD Purple, you can rely on surveillance-class storage that has been tested for compatibility in a wide range of security systems. Some of our latest models, such as the WD22PURZ, WD42PURZ, and WD63PURZ, even feature improved power efficiency. Moreover, the exclusive AllFrame technology helps reduce frame loss and enhance overall video playback.

These drives are engineered specifically for mainstream surveillance systems, catering to the write-intensive, low bit-rate, and high stream-count workloads typical of such applications. AllFrame technology delivers optimizations tailored to these demanding workloads.

WD Purple drives support up to 180 TB/yr workload rate, as defined by the amount of user data transferred to or from the hard drive, annualized based on power-on hours. However, the workload rate may vary depending on your hardware and software components and configurations.

For storage capacities ranging from 1TB to 3TB, WD Purple drives support up to eight bays, while 4TB and above models support up to 16 bays. These higher-capacity drives also employ tarnish-resistant components, making them suitable for harsher environments.

It's important to note that the stated storage capacity of 1TB represents one trillion bytes, but the actual user capacity may be less, depending on the operating environment.

In summary, WD Purple drives are the right choice for the right job – surveillance applications. With their engineering specifically tailored to withstand the rigors of NVR environments, improved power efficiency, and exclusive AllFrame technology, these drives offer reliable, surveillance-class storage that can handle the demanding workloads of modern security systems.
