Confirmation bias, the author is a Infrastructure Architect, so he sees the problem as such.

> Infrastructure build-out and optimization strategy is something I know a great deal about. It’s what I do as my day job as an Infrastructure Architect at IBM — understanding what our customers need to do in order to minimize their infrastructure overhead in terms of systems, storage, networking and facilities as they plan for further growth.

And yet he seems to believe petabytes are bigger than exabytes. This and the rest of the text makes me believe he doesn't know perfectly his subjet, to say the least...

Storage is cheap, and getting cheaper by the day. I don't think there's any reason to believe it's not going to continue that way in the foreseeable future.

EDIT: to give some numbers to the argument, I know that two years ago you could buy one petabyte (that's one million gigabyte) worth of storage for less than a million $.
