Why storing data in DNA is better than in hard drives

Patrick Nelson | March 23, 2015
New error-correcting DNA sequencing and other improvements could signal the writing on the wall for hard drives.

Synthetic fossils
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.
