Well, if storage that small was ever needed, you could store multiple bytes in each atom, based on spin. The more precisely you can measure and change the spin of an atom, the greater storage density you can have, so there fundamental limit is the limit of measuring the spin of the atom, not just the number of atoms in a given array.
