Looking at the Backblaze blog posts where they break down the cost of building their "storage pods", the $/GB cost of storage has hardly dropped since 2011: https://www.backblaze.com/blog/backblaze-storage-pod-4/ https://www.backblaze.com/blog/backblaze-storage-pod-4/. So at some point storage costs will hit a pretty inelastic floor price and then things will get very interesting for companies that advertise free or very low cost "unlimited" storage as their monthly costs will increase with every extra GB that their customers upload. It's safe to predict that other photo storage & sharing sites will follow Everpix in going under. E.g., Shoebox (http://shoeboxapp.com/ http://shoeboxapp.com/) seems to have the exact same business model as Everpix so I can't see them surviving long-term unless they kill their free plans. David Rosenthal (http://blog.dshr.org/ http://blog.dshr.org/) also has lots of good info on the economics of long-term storage.
