A note for those unaware, consumer grade NVME devices (basically all m.2 formfactor drives from my experience) only support a single namespace. If you want to explore creating multiple namespaces you will need an enterprise grade u.2 drive.
Some u.2 drives even support thin provisioning, like how a hypervisor treats a sparse disk file but for physical hardware.
