Disclosure: I work on Google Cloud.
NVMe is (now) a more general purpose "speak to flash like things". This Optane memory stuff is made of "flash", but unlike our Local SSD offering (or AWS's i3) it's at a latency and throughput closer to DRAM.
Despite it being marketing material, I find the pyramid diagram [1] helpful. This blog post is about "Optane Persistent Memory".

- ssvss 8y agoWhat is its latency compared to RAM, 10X ? Most latency comparisons mentioned in other comments compare RAM to pcie based optane memory, not the DRAM optane memory. Edit: Article[1] here says the latency was 40µs with 13M IOPS, if you consider RAM latency to be 100ns[2], then it looks like 40X [1] - https://blogs.technet.microsoft.com/filecab/2018/10/30/windows-server-2019-and-intel-optane-dc-persistent-memory/ https://blogs.technet.microsoft.com/filecab/2018/10/30/windo...
