Glass-powered data archive: Microsoft fiction? no, 10,000-year storage via laser writing
Microsoft researchers have demonstrated embedding about 4.8 TB of data into ordinary borosilicate glass using laser-written voxels, with data longevity exceeding 10,000 years. The work, part of Project Silica, uses birefringent and phase-voxel techniques to write/read data, significantly improving archival storage prospects, though writing speeds are far slower than hard drives or SSDs and cost/media availability remain barriers to commercialization.
