Western Digital WD Purple 4TB Surveillance Hard Drive – 3.5" SATA III, 256MB Cache, 24/7 NVR Ready

Your NVR's been dropping frames at 2am, or that desktop drive in the security closet is cooking itself in the heat. You don't need another generic platter shoved into a surveillance box.

The WD Purple 4TB is built for exactly this: 24/7 always-on recording, up to 64 cameras, the vibration and heat swings of a real NVR environment. AllFrame technology keeps video playback smooth instead of stuttering through dropped frames. You get 150MB/s sustained transfer, a 256MB cache, and a 1.5-million-hour MTBF rating so it's still writing cleanly in year three.

SATA III (6Gb/s) interface, 3.5" form factor, 5400RPM. Fits standard NVR and DVR bays. Western Digital backs it with a 3-year limited warranty.
