well there are 1tb memory machines not sure if a 32 gb ssd cache would help.

  The 32GB one from this article is the consumer product with the same Optane technology as the enterprise/datacenter one. The DC-P4800X (the datacenter one) has 375GB, 750GB, and 1.5TB variants[1]. So, no, if you have 1TB of memory a 32GB Optane SSD isn't going to make a difference, but if you have 1TB of memory, you're not the target for the 32GB consumer version, you're the target for the 375GB+ datacenter version.

    > you're the target for the 375GB+ datacenter version Keeping in mind that that version costs $4/GB, which is about half the price of adding more RAM. Which means that while it can be good storage for ZFS or a database, it's still not a particularly effective cache in such a machine.

      It costs $4 per GB today. In 6 months it will probably be $3, and in a few years it will be $2. Meanwhile RAM will still be $8 per GB or more. Also 64GB dimms are around $13 per GB, and have been around that price for awhile.

      well at 1tb memory there aren't that many dimm slots free and some processors also don't support that much more. but still what I wanted to say is that it is prolly more useful as a ssd read cache. and not to have it behind your big memory.
