Cloud Storage for $2 per TB per month
Offtopic question : I went through their website, and I have no idea about blockchain. I have gone through the documentation and almost everything they are doing is possible without it as well. Cryptoproofs for storing data, smart contracts et al - not sure if it is different from regular encrypted deduplication done regularly with standard per hour/ per minute billing. Also, Siacoin for payment, not sure if it is the most optimal way. 
I think I am missing something, would be glad if someone can point me in the right direction.
