The WD Purple 2TB 5400 RPM Surveillance Hard Disk Drive is crafted specifically for the demanding needs of video surveillance systems. With a capacity of 2TB, this drive provides ample storage for recording and archiving video footage from surveillance cameras, making it a reliable choice for medium-scale DVR/NVR systems.

Operating at a rotational speed of 5,400 RPM, the drive ensures efficient data access with an average latency of 5.56 ms. The SATA 6Gb/s interface supports data transfer rates up to 6Gb/s, facilitating smooth and reliable video streaming and recording.

The hard drive features a 64MB cache, which helps to enhance performance by buffering frequently accessed data, thereby reducing latency and improving overall system responsiveness. It uses a 512e (512-byte emulation) sector size for broad compatibility with various storage systems.

Designed for continuous, 24/7 operation, the WD Purple drive is optimized to handle high-write workloads typical of surveillance environments. It supports high-definition video streaming and recording from multiple cameras, making it suitable for environments requiring constant data capture and storage.

The drive's reliability is underscored by a mean time between failures (MTBF) of 1 million hours and a low error rate, ensuring long-term durability and data integrity. It operates within a temperature range of 0°C to 60°C, accommodating typical surveillance setup conditions.

With power consumption figures of 4.5W during active use and 3.5W when idle, the drive is energy-efficient while delivering consistent performance. Its dimensions (1.028 inches in height, 4.00 inches in width, and 5.79 inches in depth) and weight (approximately 1.51 lbs) make it a compatible fit for standard surveillance system enclosures.

The WD Purple 2TB Surveillance Hard Disk Drive also features Advanced AllFrame technology, which enhances video playback by reducing frame loss and improving overall video quality. This makes it a highly suitable option for video surveillance systems that require reliable, high-performance storage.
