Is Glass the Future of Storage?

"If we carry on the way we're going, we're going to have to concrete the whole planet just to store the data that we're generating," explains a deputy lab director at Microsoft Research Cambridge in a new video. Fortunately, "A small sheet of glass can now hold several terabytes of data, enough to store approximately 1.75 million songs or 13 years' worth of music," explains a Microsoft Research web page about "Project Silica". (Data is retrieved by a high-speed, computer-controlled microscope from a library of glass disks storing data in three-dimensional pixels called voxels):Magnetic storage, although prevalent, is problematic. Its limited lifespan necessitates frequent re-copying, increasing energy consumption and operational costs over time. "Magnetic technology has a finite lifetime," says Ant Rowstron, Distinguished Engineer, Project Silica. "You must keep copying it over to new generations of media. A hard disk drive might last five years. A tape, well, if you're brave, it might last ten years. But once that lifetime is up, you've got to copy it over. And that, frankly, is both difficult and tremendously unsustainable if you think of all that energy and resource we're using." Project Silica aims to break this cycle. Developed under the aegis of Microsoft Research, it can store massive amounts of data in glass plates roughly the size of a drink coaster and preserve the data for thousands of years. Richard Black, Research Director, Project Silica, adds, "This technology allows us to write data knowing it will remain unchanged and secure, which is a significant step forward in sustainable data storage." Project Silica's goal is to write data in a piece of glass and store it on a shelf until it is needed. Once written, the data inside the glass is impossible to change. Project Silica is focused on pioneering data storage in quartz glass in partnership with the Microsoft Azure team, seeking more sustainable ways to archive data. This relationship is symbiotic, as Project Silica uses Azure AI to decode data stored in glass, making reading and writing faster and allowing more data storage... The library is passive, with no electricity in any of the storage units. The complexity is within the robots that charge as they idle inside the lab, awakening when data is needed...Initially, the laser writing process was inefficient, but after years of refinement, the team can now store several TB in a single glass plate that could last 10,000 years. For a sense of scale, each plate could store around 3,500 movies. Or enough non-stop movies to play for over half a year without repeating. A glass plate could hold the entire text of War and Peace - one of the longest novels ever written - about 875,000 times. And most importantly, it can store data in a fraction of the space of a datacenter... Thanks to long-time Slashdot reader Kirschey for sharing the article.
