About this tag
Glass archival storage, also known as Project Silica from Microsoft Research, uses femtosecond lasers to encode terabytes of data inside borosilicate glass. Accelerated aging tests suggest these inscriptions can survive for at least 10,000 years under typical storage conditions. This technology moves from laboratory curiosity to a demonstrable archival platform, offering a durable, long-term solution for digital archiving. Discussions on WindowsForum cover the technical details, potential applications, and comparisons with other storage media, highlighting its promise for preserving data over millennia.
