Card speed stays at high speed during boot up while other UHS-I compatible card switched to ultra high speed.
It only changed to ultra high speed after remove and reinsert the card.
If the card is used as boot/system drive, it is not allowed to be removed during runtime therefore no performance gain since the speed stays at high speed.
