Research has suggested that diamond-based storage technology could preserve vast amounts of information for up to millions of years. 

The work carried out by a team at the University of Science and Technology of China achieved a new record for storage density in diamonds, at 1.85 terabytes per cubic centimeter.

As impressive as the storage capacity is, the researchers believe this can be eclipsed by the staying power. It has been claimed the diamond system can hold data for millions of years, due to the technique used to encode information within the atomic structure of the diamond.

As published in Nature Photonics, the scientific breakthrough extends beyond the significant density capacity with marked improvement in read times. The team indicated high-speed readout showed a fidelity of over 99%.
