WD Purple 3.5" 1TB, 5400 RPM, 64MB, SATA III Hard Drive for Surveillance

The WD Purple WD10PURZ is a 3.5-inch internal hard drive engineered specifically for surveillance applications. It is built to operate reliably in 24/7, always-on environments common to home or small business security systems. Featuring AllFrame technology, the drive is optimized to handle simultaneous recording from multiple high-definition cameras, which reduces frame loss and improves video playback. Its design prioritizes the write-intensive workloads and long-term durability required for continuous video recording over standard desktop drive functionality.

This drive provides a storage capacity of 1 TB and connects via a SATA 6Gb/s interface. Performance is delivered through a 5400 RPM spindle speed and a 64 MB cache, which facilitates consistent data streaming from security cameras. The drive is rated for a workload of up to 180 TB per year and has a Mean Time Between Failures (MTBF) of 1,000,000 hours. These specifications make it suitable for continuous data recording and archiving in compatible surveillance systems.
