In any case if storage (for games) is what you're after and you deliver the game for free, there are specific online services for that nowadays. Gamejolt for example:
http://gamejolt.com/
or itch.io which can also be used to sell a game:
https://itch.io/
Or good old indiedb of course. Nicer ways than dropbox in any case, but dropbox of course works just fine for development/preview builds
