The current forecasts don't predict cost parity for the next few years. I wouldn't speculate as far out as ten.

What you'll see is that spinning rust will increasingly become used for cold(er) storage due to still offering cheaper bytes, and (relatively) ever increasing cost of IO (you get one spindle per il unit, but at increasing capacity, with barely a change in sequential throughout and no improvement in random access). This is happening in data centers now, either through explicit product tiring or clever offloading.

> spinning rust

As the storage medium in this new tech is graphene, do we call it "spinning coal"?

Graphene is not the storage medium.

It protects the storage medium (iron-platinum alloy), which cannot be used without a protective layer, due to corrosion and scratching risk.

Your comment brilliantly illustrates the downsides of the hype.

I would assume they will go away pretty fast because of power usage.

SSDs are currently targeting performance because of the cost, but it seems possible to make them even more (and much more) power efficient when used as high latency storage.

For enterprise servers (I'm aware they are not relevant for AWS/GOOG etc), more and more often high-end machines are offered as SSD-only - for such price bracket SSDs price is already not an issue.
