That is why I'm looking at a new SSD for my laptop. But this new tech looks pretty good. I watched the full presentation with some forward skipping and I noticed a few things. They brag how it is faster than NAND Flash (uh, what wouldn't be faster than that?) and denser than DRAM... well isn't Flash denser than DRAM, by a lot?
So they carefully avoided saying the technology is not as dense as Flash and not as fast as DRAM. So it won't be replacing DRAM directly. Since it is not as dense as Flash it likely won't be replacing that unless it is a *lot* faster which they seem to be saying it is. But clearly it will be at a price premium over Flash SSDs. It will also be sold in DIMMs to plug into motherboards but not as main memory, rather to bypass the slow SATA interfaces.
I guess I won't be plugging a 3D X-point SSD into my laptop for $250. But we'll see what my next computer has for storage... assuming it isn't a phone. Heck, the main use of this memory may well be in the server world and it may never make it to the consumer market.
