Scientists report successful tests of a new memory device that could allow terabytes (1,099,511,627,776 bytes) of data to be stored without corruption for a billion years or more. The team claimed that it is possible to build storage devices capable of carrying 1TB of information per square inch, making it more effective than current techniques. The data will also be almost incorruptible.
The device is an iron nano-particle that measures 1/50,000th of the width of a human hair, enclosed in a hollow carbon nano-tube. The iron can be shuttled back and forth within the tube as a way to store data. Conventional Flash memory usually fails after three to five years.
