Not surprisingly, the technology isn't quite ready for prime time. At the moment, this storage only works in extremely clean conditions, and then only in extreme cold (77 kelvin, or -321F). However, the approach can easily scale to large data sizes, even if the copper is flawed. Researchers suspect that it's just a matter of time before their storage works in normal conditions. If and when it does, you could see gigantic capacities even in the smallest devices you own -- your phone could hold dozens of terabytes in a single chip.
