Ive never understood why we still partition drives so much..its one spindle..sure, a hige filesystem might cause an edge performance issue..but..its one spindle. / works. ? If there is a fundamental reason why we still partition things like we only have 10, 20, or 40Mb RLL. or slightly larger ESDI drives from back in the day..im willing to learn.
