MICROSOFT'S NEW 10,000-YEAR DATA STORAGE MEDIUM: GLASS

Summary from the TLDR newsletter

Microsoft's Project Silica is a working demonstration of a system that can read and write data into small slabs of glass with a density of over a Gigabit per cubic millimeter. The system can write up to 4.84TB in a single slab of glass of 12cm x 12cm x 0.2cm in about 150 hours. The main draws of the technology are that it takes no energy to preserve data and the data can be retrieved rapidly if needed. The glass also offers extreme stability, with experiments suggesting the data would be stable for over 10,000 years at room temperature.
