Keeping Data For A Long Time

Optical storage has also been used for long-term data retention and environmental stress tests indicate that the latest generation of Blu-ray optical media should have an expected life-time of at least several decades.  At the Creative Storage Conference Bill Cubellis from Sony said that properly made archival grade optical discs should have a shelf life of 50 years.  At the Open Compute Project Summit in January 2014 Facebook presented a 1 PB Blu-ray disc storage system prototype with 10,000 discs.  Facebook estimated that this system would reduce the storage costs by 50% and the energy consumption by 80% compared to their current cold storage system (probably HDD based).
