About the WD Purple 4TB Surveillance Hard Drive
Designed for 24×7 nearline surveillance workloads with an annual workload rating of up to 180TB/year, the WD Purple 4TB Surveillance Hard Drive (part number WD43PURZ) delivers sustained, reliable performance in demanding DVR and NVR environments. Western Digital engineered this drive specifically for continuous video recording applications, making it the preferred choice for storage architects and IT procurement teams deploying large-scale camera networks across enterprise facilities.
The WD Purple series supports up to 64 camera channels and manages up to 8 simultaneous HD streams, enabling efficient multi-camera surveillance infrastructure without performance bottlenecks. With a 3.5-inch form factor and 64MB cache buffer, this Western Digital drive integrates seamlessly into standard surveillance appliances while maintaining low power consumption—5.3W during read/write operations and just 0.4W in standby mode. The drive operates reliably across industrial temperature ranges (0°C to 65°C operating; -40°C to 70°C non-operating) and withstands operational shock loads up to 30G during read and 50G during write cycles, ensuring durability in challenging deployment conditions. CMR recording technology and SATA 6Gb/s connectivity provide proven compatibility with DVR/NVR appliance file systems and ATA streaming protocols.
