In my honest opinion the winner in this race is going to have to be much lower with the rates they charge individuals. For example when Google first started providing cloud storage, I got in with a simple $20/year for 80gb however now that I am grandfathered I'm ok but others aren't so lucky, paying monthly at rates 2 to 3 times higher than this. With so many to choose from and with the price of drive storage at an all time low, there is absolutely no reason these companies need to charge these kinds of rates.
