Well trick is optane was terrible as ram and pricey as storage. From what I can tell it was targetted: * where persistence was important, better than ram * for cases where more ram didn't help * for cases where adding multiple NVMe didn't help * for cases where QD1 was very important (as opposed to qd32 throughput). * for cases that didn't need too much storage, which would break the bank I got close for various database use, zfs caches, etc. But never quite beat buying more ram or 2-4x the NVMe. I tried. It was a pretty narrow niche.
