1) When it happens, and is fully supported, Storage Class Memory will be a Big Deal. (Relatively huge, nonvolatile, fast memory with a direct, fast pipe to the CPU--no SATA interrupt bottleneck bus.) 2) Pricing, as well as performance, will have to be somewhere between Main Memory DIMM and SSD/Flash Memory. 3) "Full Support" means both the Processor and the OS need to be aware, and to be fully realized, the application stack needs to exploit. This will not happen in the next two years, but over time, it will offer 10x to 100x or even more, performance boost. To me, Storage Class Memory architecture (HW, OS, and Application) is the next revolution in computing. So far, IMHO, Optane is an evolution, and nothing more than a nonvolatile DIMM. Huh?
