WD Purple 4TB Surveillance Hard Drive WD44PURZ 5400RPM SATA 6Gb/s 3.5-inch

The WD Purple 4TB (WD44PURZ) 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 5400 RPM with 64MB cache and SATA 6Gb/s interface, it supports up to 64 simultaneous AI-enabled camera streams without dropped frames.

The drive uses SMR (Shingled Magnetic Recording) recording and is rated for 180TB/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. NASware-based firmware tunes error recovery and vibration compensation for multi-camera recording environments.

Omnixon Global supplies the WD Purple 4TB (WD44PURZ) for surveillance infrastructure projects across the UAE, Saudi Arabia, Qatar, and wider GCC and MENA. Suitable for smart city CCTV deployments, enterprise campus security systems, retail surveillance networks, and government facility monitoring projects requiring reliable continuous recording.
