Verbatim

Verbatim M-Disc™ optical media is the new standard for digital archival storage. Unlike traditional optical media, which utilize dyes that can break down over time, data stored on an M-Disc is engraved on a patented inorganic write layer — it will not fade or deteriorate. This unique engraving process renders these archival grade discs practically impervious to environmental exposure, including light, temperature and humidity.

ISO/IEC 16963 standard longevity tests have proven the durability of M-Disc technology, and it withstood rigorous testing by the US Department of Defense. Based on ISO/IEC 16963 testing, M-Disc media has a projected lifetime of several hundred years.
