The synthetic fossils were subjected to heat in order to replicate chemical degredation, and the researchers were still able to decode the DNA. It worked, although the test-accelerated time period was only a month.
Any errors were corrected through Reed-Solomon codes. These are non-binary cyclic error-correcting codes, as are used in QR Codes, and ironically, CDs and DVD discs.
One gram of DNA can store the equivalent of 14,000 Blu-ray discs, says Victoria Woolaston, writing about the DNA data storage in Mailonline.
So add space savings to the potential for a million years, or more of storage and hard drive makers should be petrified.
