On the other hand...
Plenty to agree with in this article, not least that "Files are at the heart of any business".
However, let's try a different thought experiment than the outcome Andres forsees ("IT leaders...should pick a single file system that caters to [all their workloads]"). What if that can't happen. What if, through a combination of vested interests, intransigence, disagreement or whatever, there never is convergence on a single platform for all information. After all, there isn't a single operating system for business. No standard PC or tablet.
How does that change the problem?
IT would have to deliver a very different sort of solution. A way of insulating the business from the choice of storage. (In effect, doing the exact opposite of what - if I read it right - Andres is arguing for). And that would mean IT having to meet the business half way. Instead of looking at files in terms of sizes and download speeds, duplication and backup, IT and the business are going to have to work together on a way to figure out what stuff actually IS. What's important, what's not. What matters to whom, where, and how they can be most appropriately enabled to access it. And where should files live.
Once users feel they have control of something, it's incredibly difficult to oust it. I'd argue that the right strategy for IT is to express a preference, sure, from an IT perspective - but at the same time, consider what a long-lasting co-existence might actually look like, and what might be required to enable it. The end result might actually be the most effective solution, even if it involves unfamiliar choices.
