A four-year initiative is working to build a small device able to write data onto DNA-like polymers and a parallel device capable of reading the polymer-stored data. The initiative seeks to “present a clear and commercially viable path to future deployment at the exabyte scale” within 10 years. An exabyte is equal to 1 billion gigabytes.
