That's not really the point of my original question.
Full disk, or a partition taking the full disk...

I'm yet to see any arguments from one vs the other. It seems the later
allows to put a label on the disk which can be easier later to
identify a given disk (maybe..)

I was more concerned with experience regarding a difference in speed
if any. At least with a full disk, the data is always aligned with the
beginning of the disk !
