This article has a lot of good information, but its weirdly sensationalistic tone detracts from it. I appreciate learning more about 3D Xpoint and Nantero, but SSDs are not a "transitional technology" in any real sense of the word, and they won't be displaced by anything in 2016, if nothing else because it takes multiple years from volume capability to stand up a product pipeline on a new memory technology, and more years to convince the enterprise market to start deploying it. The most solid point the article makes is that the workload-specific performance of SSD-based storage is still being explored, and we need better tools for it.
I got the sense that it was a PR hit for Nantero, bought and paid for. Notice the arc of the article: it says "[Popular hot technology] is dead. [Big vendors] have recently introduced [exciting new product], but [here are problems and doubts about those]. There's also [small startup you've never heard of] which has [alternative product] featuring [this list of features straight from their landing page]."
Usually these types of articles are designed to lead people directly to the product that's paying for the article. Sensationalistic is good for this; it gets people to click, it gets people to disagree, and then the controversy spreads the article across the net. Seems like it's working, in this case.
Robin Harris has been advocating for the abolishment of block abstraction layer for a couple of years now and this piece is consistent with his usual rhetoric
Eh, it listed it as "promises" and talked the same way about Adesto. It's reasonable to say "this is the basic claim of the product; we'll see if they get there" without it being PR.
