    they are some pci-express connector for desktop mobo. (I have 1mini-itx at home when a pcie card + nvme U2 drive)
    I never understood why they did not just go with the U.2 plug instead of the bare M.2. Cost savings? Just give me a cable (though the U.2 cables are rather pricey compared to SATA cables) instead of having to dick around with small M.2 gum sick drives. It only clutters the mother board and having to remove drives can be an annoyance.

    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.
    Maybe a PCIe card with internal SATA ports?

    What about more data priority levels? Mark Cerny, the lead architect of the PS5 criticized the Nvme protocol for only having two true priority levels.

    They can just use a single something else anyway. It doesn't have to be NVMe. But it doesn't matter anyway as they did it

    Rotational media through NVMe. Okay then.

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

    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.
