Optane is nvme but is not NAND. Optane is bit-addressable so there’s no write amplification. Optane is not multi-level like nand so there is no performance degradation as the drive fills and there no “defragmenting” of partially erased pages like nand.

This means that a near full Optane device will be as fast as a brand new device and its endurance is multiple orders of magnitude higher. Optane devices are still the best SSD’s in existence.
