NVMe namespaces are an NVMe feature somewhat similar to a ZFS dataset, but at the SSD level. This is occasionally useful, so here’s a list based on stuff I have on hand and a thread over at STH:
| Model | Supported namespaces |
|---|---|
| HGST SN260 | 128 |
| Intel Optane 900P | 1 |
| Intel P4501 | 1 |
| Intel P4610 | 128 |
| Intel P5500 (Dell firmware) | 128 |
| Kingston DC1500M | 64 |
| Micron 9200 | 1 |
| Micron 9300 | 32 |
| Samsung 970 EVO Plus | 1 |
| Samsung PM9A3 | 32 |
| SK hynix PC601 HFS512GD9TNG-L2A0A | 1 |
| WB Blue SN570 | 1 |
| WD WDS500G2X0C (SN700) | 1 |
To check this for yourself, the disk can be queried.
On FreeBSD, run:
nvmecontrol identify nvme0 | grep "Number of Namespaces"
On Linux, ensure the nvme-cli package is installed and run:
nvme id-ctrl /dev/nvme0 -H | grep nn
