Some alternative reasoning:  When the platter is horizontal, all its weight
is on the bearings on the lower end of the spindle.  When the drive is on edge,
the platter is vertical and the spindle is horizontal, so the weight of the
platter is divided between the bearings on each end of the spindle.  Thus the
wear might be expected to be half as much, on each end.
