But wasn't the potentially transformative market intended to be "persistent DRAM" for instant-on devices removing the distinction between memory and storage, requiring DRAM-like speed rather than NAND-like speed ?
I recall their early R/W speed performance projections being far faster than what they ever achieved with Optane drives.
The products that used a PCIe X4 interface with a block storage protocol layered on top were never intended to deliver the best performance the memory was capable of.
Interesting - I wasn't aware, but even avoiding the PCI bus the performance must have been lacking as that link talks of "memory tiering". I guess this was "mid tier" somewhere between SSD and DRAM, which is a bit of a no-mans land especially in terms of conventional systems architecture ... really just a fast type of storage, or storage cache (a bit like a hybrid SSD-HDD drive).

Sure, but Intel never got to the point of packaging it as memory (DIMMs) since the performance wasn't there.
Yes, they did ship the DIMMs: https://www.intel.com/content/www/us/en/products/docs/memory...
