Yeah it's worth it. Probably the best deal for cloud storage you can get since they accept RAW files and the photo storage is unlimited. Videos are different, you get 5gb of that but I paid a dollar for 100gb on the video side. I don't really need the video side as much as video though.
I spent a lot of time looking into cloud storage deals for my photography since my laptop was running out of space, as were my SD cards. The main thing for me was zero compression on the files and a good pricing per TB. Since Amazon's unlimited as well, it won over the rest.
