Purchased this for a church security camera system which had a Toshiba HDD crash for no known reason. Searched for a larger HDD with characteristics I needed, like write priority and capability to take the use at high volume times. This was the one. So far it has worked as well as we had hoped.

I chose this over the Seagate Surveillance HDD, because I have a good experience with WD products in general. So far, I have been using this HDD for a few months now and this product works very well in our 8 Channel DVR. Its set to record 24/7, so it can handle being recorded continuously.

We have always had VERY good experiences with these "Purple" hard drives and up to this point have never had a bad one or a failure out of box! We tried others with regards to CCTV and wasn't the case. Nothing but good things to say about the Purple Hard Drives... won't use anything else.
