Tiny crystals could hold the key to creating computers with massive storage capacity, scientists believe.

The crystals could be used as storage devices for desktop computers capable of holding 100-times more data than current systems.

Scientists at the University of Edinburgh have been using low-energy lasers to make salt crystals in gel.

The development could allow users to store a terabyte of data in a space the size of a sugar cube within a decade.

This would be enough to hold the equivalent of 250,000 photographs or a million books.
