WD Purple 3.5" 3TB, 5400 RPM, 256MB, SATA III Hard Drive for Surveillance

The Western Digital WD Purple hard drive is specifically engineered for surveillance systems requiring continuous, 24/7 operation. It incorporates AllFrame technology, which works to improve write performance and minimize frame loss in multi-camera, high-definition video recording environments. Built to function reliably in systems with up to eight drives, this HDD is constructed to withstand the elevated thermal and vibrational stresses common in surveillance hardware. Its standard 3.5-inch form factor ensures compatibility with most desktop-class NVRs and DVRs.

This model offers 3 TB of storage capacity and connects using a SATA 6 Gb/s interface. It functions with a 5400 RPM spindle speed and is equipped with a 256 MB cache to manage simultaneous data streams from multiple cameras. The drive is rated for a workload of 180 TB per year and has a Mean Time Between Failures (MTBF) of one million hours, metrics that reflect its design for constant data writing. S.M.A.R.T. technology is supported for proactive drive health monitoring, providing system administrators with critical operational data.
