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. Designed for widely distributed large data such as scientific images, video, and other commercial application object data, Verbatim M DISC BD-R DL media have a storage capacity of 50GB – allowing you to use fewer discs while archiving your files. - Projected lifetime of several hundred years (based on ISO/IEC 16963 testing) - Stored data is engraved – ultimate archival solution - Impervious to environmental exposure, including light, temperature and humidity - Withstood rigorous testing for durability by US Department of Defense - 50GB storage capacity - 10-Year Limited Warranty More information: Features | Type | BD-R DL |  | Native capacity | 50 GB | | Optical disc diameter | 120 mm | | Data retention | 10 year(s) | | Product colour | Blue, White | Writing speed | BD-R write speed | 6 x |
