Installer notes

This is a standard 3.5in SATA drive, so it drops into any recorder or storage chassis with compatible SATA bays — check the recorder's supported drive list and per-bay capacity limit before ordering multiple units for a multi-bay NVR build. The 180TB/year workload figure and 8,760 power-on hours rating are what separate this from a desktop drive dropped into a DVR: continuous sequential writes across many camera streams is the intended use case, not an edge case.

For high channel-count NVRs or RAID arrays where sustained write throughput across several drives matters, the 256MB cache and 180MB/s sustained rate are the numbers to check against your total camera bitrate budget.
