Ich wuerde diesen Thread gerne nutzen, um ein paar interessante Daten von NVMe-Modulen zu sammeln, die smartctl bequemerweise ueber sie preisgibt: Einerseits die "Power States", und andererseits die "Namespace Formats", die oftmals unterstuetzt werden.
Alternativ dazu nehm ich auch gerne eine moeglichst vollstaendige Datenbank von NVMe-Devices, die diese Daten enthaelt
Die Daten kann man mit diesem Einzeiler auslesen:
for d in /dev/nvme?; do sudo smartctl --xall $d; done | LC_ALL=C sed -rn -e '/^(Firmware Version|Model Number): /p' -e '/^Supported Power States/,/^=== /p'
Ein paar Devices in meiner "Reichweite" als Ansporn/Startschuss:
