Cheapest 4TB I could find. Not loud. The 5,400RPM speed isn't an issue if you are just using this for video/picture storage. Make sure you get this one (ST4000DM004) and not the older, less reliable and slightly cheaper ST4000DM005.
In hindsight, I would have gotten a 7200 RPM drive just to get a little faster speeds, but this does not disappoint. I usually get about 150MB/s when transferring files in Windows Explorer. I have no issues with this though, it is a well made HDD.
