Intel's new Optane technology is impressive. Likely to replace flash SSDs over time with something much faster more durable. Currently expensive though.
I guess the first thing if it really is close to DRAM speed is a switch from eg 8 GB DRAM + 500 GB SSD with a small page file on the SSD to 2 GB DRAM + 500 GB Optane with a large page file on the Optane. Which would perform better and be cheaper?

(how efficient is paging in Windows, anyway? And how much more expensive will optane be than flash, and how much cheaper will it be than dram?)
-
AFAIK pagefiles are as fast as the HDD but I don't know exactly how it all works, maybe it is slower

just depends on how fast optane is relative to the SSD

The PCI-E SSDs are several gigabytes a second and climbing

last time I benchmarked my dram it was 14 gbs and that was almost a decade ago. I'd bet most programs for ordinary people don't need a tenth of that even today
-
Interesting possibility of ditching the RAM completely if people really don't need the speed
