Hello - were you able to get this working?
I also have a p420m I would like to use in my unraid box.
I see is showing up in system devices as [1344:5161] 04:00.0 Mass storage controller: Micron Technology Inc RealSSD P420m (rev 03)
but thats about it - cant seem to use it as a drive.
Any assistance would be appreciated
Multiple cache pools. I know this is currently possible with the unassigned plugin and btrfs - But it would be nice for it to be native in the web GUI.
