Western Digital wd64purz-74bwuy0 6TB Surveillance Hdd

Product Description

The WESTERN DIGITAL wd64purz-74bwuy0 is a 6TB, 3.5-inch SATA hard drive engineered for continuous-duty surveillance applications. Built on CMR (Conventional Magnetic Recording) technology with a 256MB cache and transfer rates up to 175MB/s, it is designed to sustain the high-write, always-on workloads typical of DVR and NVR systems. An MTBF rating of up to 1 million hours and a workload rating of up to 180TB per year make it a purpose-built storage solution rather than a repurposed desktop drive. Licensed CCTV and security system installers are the primary users of this drive.

This drive is intended for mainstream residential and commercial surveillance installations running 24/7. It supports up to 64 single-stream HD cameras, making it suitable for both small-site DVR setups and larger multi-bay NVR enclosures. The operating temperature range of 0 degrees F to 65 degrees C accommodates the elevated internal temperatures common in always-on recorder enclosures. Tarnish-resistant components extend service life in environments where ambient conditions are less than ideal.

Compatibility

Installation Notes

Installation should be performed by a qualified security system technician or integrator. Power down the recorder completely and discharge any static before handling the drive. Secure the drive using the enclosure manufacturer's recommended mounting hardware and verify SATA data and power connections are fully seated before restoring power. Follow the recorder manufacturer's drive initialization and RAID configuration procedures before placing the system back into service.
