WD Purple 2TB SATA surveillance drive
The WD Purple WD20PURZ is a 2TB 3.5 inch internal hard drive built for video surveillance systems. It spins at 5400 RPM with a 64MB cache and connects through a SATA 6.0Gb/s interface. The drive is engineered for write-intensive, low bit-rate workloads typical of security recording.
Fits standard 3.5 inch drive bays
The unit measures 147.00mm long, 101.60mm wide and 26.10mm high, matching the standard 3.5 inch form factor. It requires a SATA power connector and a SATA data cable from the host controller. AllFrame technology and ATA streaming support reduce frame loss, freeing the system from managing video stream integrity in software.
Suits installers building
The 180TB per year workload rating and multi-bay support make it appropriate for continuous recording in home or small-business surveillance. It is not intended for general-purpose desktop storage, high-performance gaming libraries, or applications that demand low-latency random access. Buyers needing faster access times or higher sequential throughput should consider drives designed for those workloads.
