Eventual Optane replacement tech?

[nabsltd]

With Intel no longer producing new Optanes, what are you using for the old Optane perfect use case (very low latency write cache)? I know many here are hoarding Optanes and just using them, but eventually that won't be an option.

I've been watching announcements from manufacturers, and everything seems to be about huge data density and much faster connections (e.g., 128TB U.2 drives at PCIe 5.0x4). I can't afford to replace every disk with similar-sized NVMe, so I look to use cache in front of spinners, and Optane is really good at that.

Has anybody heard of new tech announcements for something similar to Optane (i.e., low latency plus insane endurance)?

I have searched for articles on industry shift away from M.2 NVMe to U.2/U.3/ES.x for enterprise and/or data centers.
No articles ... just seems the writing is on the walls.

M.2 NVMe just suits my 10 year old lab set up.

Many of the write performance use cases are easily served by CXL-enabled devices that can ingest to DRAM that has PLP, then data is dumped to slower storage.

TL;DR: Return of the "NVDIMM-N" (in quotes, because it's not really NVDIMM-N, but functionally very similar)

I have seen some announcements for new enterprise SLC NAND NVMe drives to try to fill in for Optane in some uses, but I suspect those are going to be uncommon and correspondingly hard to pick up used in the future.

As I suspected, everybody is using what they already have hoarded, and there isn't anything really on the roadmap for a semi-large (100-500GB) storage device that can act as fast read cache and do well at write cache.

What I'm also wondering is if EDSFF will really take off for data centers, and so 10 years from now there will be no used devices with usable form factors without buying the whole system at once.
