Smart video surveillance is on the rise, bringing increased storage requirements along with it. For example, high-resolution cameras are capturing multiple video, picture and metadata streams per camera; AI and video analytics are placing new demands on quantity, quality and retention of video data; and deep-learning solutions are needing more video to train AI algorithms, all while video-surveillance-as-a-service (VSaaS) customers are needing purpose-built storage to efficiently manage this data at scale.
The 22TB WD Purple Pro CMR HDD with OptiNAND technology delivers big capacity to address these trends, in a purpose-built enterprise-class drive supporting video analytics servers, and AI and deep-learning systems. The drive features Western Digital’s exclusive AllFrame AI technology that supports 32 AI streams for deep-learning analytics within the system while helping to reduce dropped frames.
WD Purple Pro drives are optimized to handle up to 64 single-stream HD cameras as well as many of the latest smart cameras that transmit multiple streams. It offers high reliability with a MTBF of up to 2.5 million hours 2 for advanced smart video solutions that operate in 24/7 environments. The WD Purple Pro HDD family now comes in 8TB-22TB capacities.
