21 Oct Life expectancy for digital data storage
National Academy of Technologies of France (NATF) 2010
Our society generates an ever growing mass of information which raises a serious concern over its efficient, long-term storage and archiving (these are two distinctive notions!). The material used for the digital support and hard discs have a limited lifetime of roughly 5 to 10 years. The life expectancy of recordable optical digital discs (RODDs) seems better but, still, appears also limited to about 10 years. Besides the detailed analysis of technical aspects of various available storage and archiving technologies, the report concentrates on possible data conservation strategies. It also suggests certain approaches that could lead to RODDs with notably better life expectancies. A set of 4 recommendations is issued at the end of the report.
