This drive works great and has extended my storage capacity almost double. If you are a do it your selfer like me, make sure if you decide you want to add hard disk drives to your system that you are not tempted by really cheap prices for hard disk drives shown on other computer/on-line sites. Often times those hard drives are good hard drives but they are cheaper because they are only 5400 RPM hard drives and have a slower data transfer rate. Most of the DVRs (I learned the hard way) require 7200 RPM hard drives with fast data transfer rates. If you want to be sure, purchase them from Security Camera King and it may save you some grief.

This really extended my storage potential. Works great, was easy to install, and have had no problems.

We wanted to extend the recording storage capacity of our DVR so we could hold more archived footage without having to delete it and write over it so quick. A 3 TB SATA hard drive is definitely the solution for us. This should keep us running for a very long time without the need for overwriting files. In fact the addition of this hard drive to our DVR should give us enough storage room so we really shouldn't ever have to make up archive DVDs anymore. The drive is easy to install and it works fast.

We recently purchased the 3 TB SATA hard drive for our DVR. After purchasing the DVR and using it for a while, we realized that we really didn't by a big enough hard drive four our application so we added this SATA hard drive. Works fast and seems reliable. It was easy to install.
