AI-Generated Deep Dive Summary
The article explores the challenges of long-term data storage and introduces M Discs as a potential solution for archival durability. Traditional media like DVDs and Blue-Ray discs are prone to degradation due to factors such as magnetic creep and physical breakdown, making them unreliable for preserving important data over decades. Professionals often rely on RAID systems or regular drive replacements, which may not be practical for home users.
The article highlights the limitations of conventional storage methods, emphasizing the need for more durable alternatives. M Discs, developed by Millenniata, claim to offer greater longevity with their unique glassy carbon technology, designed to resist oxidation and withstand extreme temperatures. While testing by Millenniata suggests a lifespan of up to 1000 years under proper conditions, independent tests by organizations like the French National Laboratory have shown mixed results.
Despite their potential, M Discs are not a perfect solution. Their durability depends on future technology's ability
