WHAT TO KNOW

• A new study by researchers at Microsoft describes a groundbreaking effort to create a permanent solution to long-term data storage using ordinary glass. Called Project Silica, the technique uses ultrafast lasers to burn data into plates of glass about the size of a drink coaster. The lasers write data in 301 layers with a total storage capacity of about 5 TB (equivalent to roughly 3,500 full-length movies). To read the data, a microscope captures images of each layer and sends the images to an AI model to be decoded.

WHY IT MATTERS

• The researchers believe their technique can preserve information for 10,000 years at room temperature, significantly longer than standard hard drives, which store data on magnetic tapes that degrade within 5-10 years. Glass also requires zero electricity to maintain, and is impervious to heat, water, radiation, and magnetic fields, all of which destroy standard hard drives. Microsoft says developing a technology that allows people to write data knowing it will be unchanged and secure represents a significant step forward in sustainable data storage.

CONNECT THE DOTS

• Project Silica is designed for large-scale archival and cloud storage rather than day-to-day consumer use. While it takes longer to write the data in glass, Microsoft argues the payoff is worth the wait, requiring a fraction of the physical space used by today’s datacenters and offering a more sustainable way for cloud providers, national archives, and media companies to preserve digital records.
