WD Purple 3.5" 4TB SATA3 Internal Hard Drive

WD Purple drives are designed to tackle the challenges posed by uninterrupted video surveillance recording. They've been specifically designed for video surveillance, so they can withstand extreme temperature fluctuations and the vibrations typical of a network video recording (NVR) environment. A standard desktop computer drive is designed to operate only in short intervals, not in the demanding, always-on environment of a high-definition video surveillance system.
WD Purple drives offer reliable video surveillance storage whose compatibility has been tested with a wide range of security systems. Exclusive AllFrame™ technology helps you reduce frame loss and improve video playback.
Greater reliability with AllFrame™
All WD Purple drives are equipped with AllFrame™ technology, which improves ATA streaming to reduce frame loss, improve video playback and much more.
Frame or video fragment loss is a serious problem when you need to view surveillance footage. All WD Purple™ drives are equipped with AllFrame™ technology, which improves ATA streaming to help reduce frame loss, improve overall video playback and increase the number of compatible drives in an NVR. WD Purple 8 TB, 10 TB and 12 TB drives with AllFrame AI support a workload of up to 360 TB/year to enable deep learning analytics compatible with AI-enabled NVRs.
Industry-leading storage.
Video surveillance you can trust. Western Digital has been offering storage solutions suited to video surveillance for over a decade. WD Purple video surveillance storage is built on drives designed for video surveillance systems that run continuously at high temperatures.
