On the route

For a vending operator, this drive fits into the NVR at the hub or local site. It is designed to handle the constant stream of video from multiple cameras. The 128 MB cache helps manage the data flow from up to 16 bays. The 180 TB/yr workload rating suggests it can handle the continuous writing required for 24/7 monitoring. It is a straightforward internal SATA drive that plugs into standard NVR hardware. The 4TB capacity provides a reasonable buffer for footage.
