Some of us are struggling just to maintain our ever-growing archive of photographs and video footage. Every few years, we have to update all our drives to newer, faster, higher capacity and more reliable ones to try to ensure we don’t lose anything. And for most of us, that’s only a few terabytes. But what if you could store half a petabyte, indefinitely?
Well, technically, it’s 13.8 billion years, but for all intents and purposes, that’s pretty much indefinitely. Researchers at the University of Southampton have developed a new technique that could allow up to 500TB of data to be written to a CD-sized “5D” glass disc. For comparison, CD-Rs store 650MB of data.
