I recently got a Synology 1815+ NAS (Network Attacted Storage) 8 bay system and I couldn't be happier with the results. My main goal was image backup, but this thing is far more that just a place to store images. Synology did a great job of creating a drive unit that is basically a server. You can upload, download, stream media, create shared users and more. I have a professional Dropbox account that I will be replacing by using this 1815+. There is no monthly fees to use Synology products. There are endless ways to use and configure this thing but the best part is I was up and running in 10 min. Seriously one of the easiest things I've ever used.
