Got a 128 gb sata III m21-stick which i mounted into case.
2. downloaded Linux Mint Cinnamon Iso to ultrabook but it landed on stick.
3. cannot delete, format. whatever action to remove. yes i added permission.
NB: Speed 1.89 gb to stick 144 sec, to systemdrive. 115 sec.

Will get NVMe stick and want to compare writing-speeds.
