Project Silica is a data storage technology project by Microsoft aimed at developing archival storage solutions for cloud-based systems, utilizing ultrafast laser optics and nanostructured glass technology to store data in quartz glass. Project Silica was needed to address humanity's need for a long-term and sustainable store technology, allowing the ability to leave data in situ.[1]

Overview edit

Project Silica was highlighted in a Microsoft Ignite 2017 keynote as part of the broader "Optics for the Cloud" initiative, which explores the intersection of optics and computer science for future cloud infrastructure.[1] The project leverages 5D optical data storage technology which employs a femtosecond laser writing process to inscribe data in fused quartz, creating a storage medium with potential longevity stretching into thousands of years without degradation. A femtosecond laser writes data on the glass, creating tiny patterns on three layers within the discs. Data is encoded in five dimensions: the three-dimensional position of the nanostructures, and their size and orientation.[2]

Capacity and Durability edit

A glass disc in this technology can hold up to 7 terabytes (TB) of data, with a potential for preserving data over extended periods. The project demonstrated the storage of a digital version of the 1978 Superman movie in a piece of quartz glass as a proof of concept.[3] The quartz glass used is low-cost and durable as well as EMF-proof, offering lifetimes of tens to hundreds of thousands of years. [1]

Development and Applications edit

The primary focus of Project Silica is to provide archival storage for "cold data" or data that is seldom accessed but stored for a long term, especially in cloud environments. Much of the work is carried out at Microsoft Research's Cambridge lab in the U.K., in collaboration with the Optoelectronics Research Centre at the University of Southampton.[4]
