LTS DHWD44PURZ WD Purple 4TB Surveillance Hard Disk Drive, 5400 RPM Class SATA 6 Gb/s 256MB Cache 3.5 Inch

The LTS DHWD44PURZ is a 4TB WD Purple surveillance-grade hard drive purpose-built for continuous 24/7 recording in security and surveillance systems. Optimized for the constant write demands of multi-camera NVR and DVR environments, WD Purple drives feature AllFrame technology to reduce video frame loss, minimize errors, and extend drive longevity compared to standard desktop HDDs used in surveillance applications.

Running at 5400 RPM with a 256MB cache buffer and a SATA 6 Gb/s interface, this 3.5-inch drive delivers reliable sequential write performance tuned for the continuous write patterns typical of surveillance footage. The drive is engineered for low vibration in multi-drive enclosures and operates across a wide temperature range to maintain consistent performance in NVR and DVR environments with limited airflow.

Key Features:

• 4TB storage capacity; provides ample recording time for small to mid-size multi-camera surveillance systems without frequent drive swaps.
