Still in the lab, "the machine" switched to using DRAM until it gets cheap enough to scale. It's really mind-boggling how much we demand of new technologies, we've refined magnetic storage over many decades. These things at least a decade to go from laboratory ... proof-of-existence to commercially competitive product.
As far as I can tell there is more than just HP's memristor based storage level, random access, non-vol memory technologies stuck in R&D pipelines right now. Eventually (or perhaps hopefully) they'll make it to market and I think will make for a more interesting state of computer hardware than there has been in some time.
We are asking a brand-new technology to catch up with stuff that has had an entire industry optimizing it for decades. It's going to take decades for a single company to get things up to speed.
