It's still grand that NVMe massively improved the world beyond "can it boot". Having 65536 different submission queues, having read/write opa take 1 rather than 6 round trips, and a variety of other improvements.
I think we still would have been stuck with a bunch of vendors making exotic expensive boutique flash storage systems for a while had Intel not come by & made a fairly sizable overhaul of the existing protocols.
