Western Digital Purple HDD SATA 4TB 5400 256MB

WD Purple 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. With WD Purple, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems.

Modern recorders now support multiple video streams per camera. WD Purple drives support up to 64 single-stream HD cameras (6TB and above), and can also support many of the latest cameras that transmit multiple streams. With so many options, you have the flexibility to upgrade or expand your security applications in the future.

WD Purple™ drives feature a workload rating of up to 180TB/year - up to three times that of desktop drives - to handle the unique demands of mainstream video surveillance DVR and NVR systems. All WD Purple drives are equipped with AllFrame technology, which improves ATA streaming to help reduce frame loss and improve overall video playback, within a multitude of security video solutions.

With an MTBF of up to 1 million hours, WD Purple drives are engineered for mainstream surveillance DVRs and NVRs that operate 24/7. With tarnish-resistant components and support for more than eight bays, WD Purple drives deliver reliable operation even in harsh environments.

Western Digital Device Analytics™ (WDDA) provides a wealth of storage device parametric operational and diagnostic data to the system. WDDA is intended to empower OEMs, system integrators, and IT professionals to better monitor and proactively manage supported storage devices to maintain optimal operation.
