Panasonic unveiled its enhanced "freeze-ray" series Data Archiver, which uses 300GB Optical Discs for long-term storage. The system was developed in collaboration with Facebook and shown at this week's Open Compute Project Summit in San Jose.
A fully-loaded freeze-ray system can pack 1.9 petabytes of data in a standard 19-inch data center rack.
In the future, Panasonic plans to increase the capacity of the Archival Disc to 500GB and eventually 1TB per disk.
