Great drive installed in a swann dvr nice and fast and 256mb cache is a great bonus very quiet compared to the factory drive that came with the dvr mostly due to being ALWAYS ON Highly recommend

Great price 2TB Hdd for my NVR. No problems.

This drive is great for my home surveillance system. Running 4 cameras on 1080p and its barely hitting 5% on disk activity. Highly recommended

Good price and works well. Haven't had a failure yet of the many I have bought.
