once setted up, Media Files from Array disks (HDD) can be copied or moved to a pool ssd, the plugin can either live switch internally to cache (/mnt/user/... access is mandatory for Media Server, Players, ...) hard cut internally file access, Player will stall and you know when to stop, start ... pool reading will be active now do nothing, you have to manually know when you want to stop, start to use pool instead array disks
