Microsoft Cutting-Edge Breakthrough: Storing Data on Glass for 10000 Years
As data storage becomes increasingly affordable, we’ve amassed vast amounts of data, ranging from gigabytes to terabytes.
Whether stored locally or in the cloud, the lifespan of storage media is limited.
In order to preserve data for extended periods, Microsoft is pioneering a new storage technology called Project Silica, which allows permanent data storage without any need for electricity.
Rather than writing data onto magnetic storage media, it encodes data into glass disks smaller than DVDs.
According to Microsoft engineer Ant Rowstron, hard drives in data centers have a lifespan of approximately five years or even less. Switching to tape storage might double this time. Regardless of whether hard drives or tapes are used, the manufacturing, powering, and data transfer processes consume time, money, and resources. The development of a more reliable and long-lasting data storage product that reduces resource consumption led to the creation of Project Silica, a glass-based data storage system.
Project Silica employs short laser pulses to write data onto glass disks. These lasers physically alter the internal structure of the glass, ensuring that even surface scratches do not affect the encoded data.
Due to the incredible stability of glass, engineers estimate that data can be safely stored for 10,000 years or longer.
A single disk has enough space to hold 1.75 million digital songs, roughly equivalent to about 7 terabytes of total storage.
Importantly, glass disks require no power to perform their function. They can be stacked on shelves and read when needed.
Ant Rowstron notes that the development of the Project Silica project takes cloud considerations into account. Specifically, it resembles a form of cold storage where data isn’t immediately accessible. The process of writing and reading data from the glass disks involves multiple stages.
Starting with the Write Lab, lasers engrave 3D pixels within the glass. When it’s time to retrieve data from the glass, a small robot moves across the shelf where the glass disks are stored and selects the appropriate one.
In the Read Lab, a computer-controlled microscope reads the 3D pixels from the extracted glass disk. Next, the data enters the Decode Lab, where Azure AI transforms the visualized data into usable digital records.
The development team estimates that Project Silica will undergo several more laboratory research stages before being ready for commercial use. However, it holds the potential to serve as Microsoft’s long-term archival storage solution, potentially replacing another Microsoft project, Project HSD.
