We don't care about (TBW/TB) at the consumer level, we care about (TBW/$), and 3D TLC was far, far cheaper per TB, so much so that TBW/$ was not a numerical advantage of Optane.

That left ONLY the near-RAM-read-latency, which is only highly beneficial on specific workloads. Then they didn't invest in expanding killer app software that could utilize that latency, and didn't drop prices sufficiently to make it highly competitive with big RAMdisks.

In 2018, with Optane drives launching around $1.50/GB and TLC flash drives around $0.15/GB, it wasn't that much cheaper. As far as I'm aware Optane had a lot more than 10x the endurance.

10x endurance and 10x latency reduction, for 10x the price. It was closer to 5x the price with the closeout firesale after it was killed.
