    NVMe drives can be partitioned by the hardware.

    There could be multiple drives on a drive and n# is the hardware partition.

        Well, for example, you need multiple partitions on a system drive. Such as swap, boot and the main partition for the OS

          The namespaces are generally not used for that, since partition table does the job.

          Nvme bakes in a lot of “just in case” functions that fancy storage engineers imagine a use case for that are in practice superfluous.

        That’s the name of it. 🙂 I was letting a dog outside and couldn’t remember the technical name.

        Under-provisioning the drive is the most common usage I’ve seen.

        Maybe passing it directly to a VM, but I haven’t tried that.
