3.5″ internal hard drive from the 2017 WD Purple Surveillance family of dedicated HDDs. This line includes 11 models from 1TB and 18TB, which are optimized for use in video surveillance systems based on DVRs and NVRs. Special firmware with AllFrame 4K technologies provides uninterrupted round-the-clock recording of video streams from numerous HD-resolution cameras (up to 64 pcs).
Supported by proprietary Western Digital Device Analytics software that continuously monitors and protects the surveillance data warehouse with advanced prevention and recovery tools. If necessary, the WD Purple WD20PURZ hard drive can be easily integrated into RAID arrays. Designed to work in storage, including up to eight drives, which makes it possible to easily and quickly scale the video storage subsystem as needed.
Equipped with SATA3 interface for full backward compatibility with SATA2 and SATA equipment. The energy-efficient controller and firmware features guarantee high efficiency and low heat dissipation (4.4 W in active operation), which increases the reliability of the system as a whole. The resource guaranteed by the manufacturer is 180 TB per year (warranty 3 years), which is equivalent to continuous recording of video streams in 24/7 mode up to 20.5 GB per hour.
