Chinese scientists have created a DVD disc capable of holding 200 TB of data

Best of all, the production of these discs is possible with DVD production equipment: it takes no more than six minutes to produce one disc. It is unlikely that this type of media will appear for free sale, but it can change the situation drastically, for instance with regard to the design of data centre architecture. Compact optical discs have a better size than hard disks and higher capacities than solid-state drives.
