WD Purple Pro 18TB Surveillance Hard Drive WD181PURP 7200RPM SATA 6Gb/s 3.5-inch

The WD Purple Pro 18TB (WD181PURP) is a 3.5-inch surveillance-optimised hard disk drive engineered for continuous 24×7 write-intensive operation in IP camera recording systems, DVRs, NVRs, and video surveillance storage appliances. Running at 7200 RPM with 256MB cache and SATA 6Gb/s interface, it supports up to 32 simultaneous AI-enabled camera streams without dropped frames.

The drive uses CMR (Conventional Magnetic Recording) recording and is rated for 550TB/year annual workload — significantly higher than desktop drives — reflecting its design for the relentless sequential write demands of surveillance recording. AllFrame AI technology reduces dropped frames and maximises the number of simultaneously supported camera channels. WD Purple Pro adds support for edge AI analytics directly on the drive, enabling deep learning inferencing at the storage tier for smart NVRs.
