      Wasn't ZNS part of the previous spec too?

        This looks a lot like RISC-V in where implementations are only required to implement the base spec...
        Prepare to see enterprise NVMe devices that support the full feature set.

            That reminds me.

            I need to research a good SATA port multiplexer to buy a couple of next time I want to upgrade my capacity. My motherboard's SATA ports are full but I've got a couple of free internal drive bays and none of my bulk-storage drives exceed half of what a SATA-III link can do.

              ZFS could make use of it. Some spinners and an SSD ZIL+Cache coming off an adapter plugged into an NVMe port.

                You should get a used SAS PCIe card and SAS to 4x SATA adapter cables. A two port SAS card can give you 8 SATA ports for ~30$.

                  There's an Apple port adapter joke in there somewhere.

                    Probably for the enterprise. I'm thinking some sort of tiered solution that will "archive" cold data or something.
