View of the hard drive
PURPLE hard drives are designed for use in video surveillance systems operating in 24/7 mode. The series offers superior performance, high capacity and long-term reliability. The drives can work non-stop in systems processing and recording audio and video, especially in professional CCTV systems, on PC platform.
The PURPLE series is based on the RED family. The modified firmware functions minimize the risk of loss of image frames due to errors, or heavy load (AllFrame), as well as the power consumption (IntelliPower).
Western Digital hard drives are recommended by all leading manufacturers of CCTV equipment.
WD84PURZ drives have a much better performance than their counterparts dedicated to PCs. The special features include:
- surveillance-class storage with minimized risk of loss of image frames
- specially designed surveillance systems
- caching algorithms tailored to the requirements of CCTV systems with a high intensity of write operations, comparatively low data rates and a large number of simultaneous data streams
- priority change for write allocation and preemptive caching policies
- TLER and ATA streaming support
WD PURPLE hard drives come with a five-year manufacturer's warranty. For applications requiring a higher workload, choose RED series drives.
