Are you asking for a definitive figure or perhaps even a tentative figure? Because the answer is infinite. Once we hit the ceiling of storage, we just add more space to accommodate our needs, there's no definite figure. I'm sure perhaps a statistician could maybe work out some kind of vague figure that would be invalidated the moment it's published. It's like asking how much oxygen is available to the human race, trees are being planted and contributing oxygen all of the time, there's no figure on how many trees there are exactly, only estimates.
