The discs of fused quartz that are used for five-dimensional (5D) data storage have been called "Superman memory crystals," and with good reason: they can hold an astonishing amount of data, and are built to last billions of years. A femtosecond laser records the data on a fused quartz crystal, writing files in nanostructured dots separated by a mere millionth of a meter. These nanostructures are what gives the storage method its "extra" two dimensions, which correlate to the size and orientation of the dots.
