How far in the future?
I used to spend time at the IBM development lab in Rochester MN. I was privy to what might be available in the next year, but I know they were working on things far more in the future. Some of these new features were beyond our current comprehension. Hard to predict the future. With storage my guess is it will be smaller and smaller containers to hold more data. and I would think that redundancy for backup will be build in. And it will be fast.
