Intel's new Optane technology is impressive. Likely to replace flash SSDs over time with something much faster more durable. Currently expensive though.

There's talk about using it as some kind of slow but persistent RAM, but I suspect it's more likely to slip right into the SSD niche.

Many levels of memory in computers: CPU (processor registers) -> L1, L2, and L3 caches -> DRAM -> Optional storage cache layer -> long-term storage (HDD or SSD) Speed and cost go down the farther you go in the hierarchy. Optane fits in the cache/SSD layer

Yeah optane might just make RAM obsolete except for high end gaming rigs or productivity stations

That will be very interesting! But it will be awfully hard to compete with the speed and cost of DRAM. Best to tackle the long-term storage layer first

As long as SSDs keep getting faster and software needs don't rise too much, I can see smartphones using barely any real RAM etc

Anyway, yeah, it's actually a pretty exciting tech. I get the impression that a lot of people are underwhelmed, but this is the biggest thing since the SSD
