I love that last graph
It nicely sums up how content-free the article is (after first explaining the basics of HDD and flash). It's mostly either an extended exercise in wish-fulfillment or pulled right from the nether regions. I hope flash succeeds and comes downmarket too, I'd like to be able to afford more, but even at QLC 16nm I don't see how it's likely to fully compete with a combination of iterative SMR (and eventually HAMR) tech, and potential future flash competitors (memristors, if they ever get off the ground?).
Flash has probably reached the point where it can perform nearly all of most consumers' needs, but businesses' need for storage will seemingly expand to fill as much as they can afford.
