This Glass Disc Can Store 360 TB of Your Photos for 13.8 Billion Years
If you back up your photos on optical disks or storage drives, there’s a good chance your data won’t last as long as you do due to things known as “disc rot” and “data rot“. But what if you want to ensure that your precious photos live longer than you? Good news: a new “eternal” storage technology may be on the horizon.
Scientists have created nanostructured glass discs that can storage digital data for billions of years.
The glass storage discs can hold a whopping 360 terabytes each, are stable at temperatures up to 1,000°C (1,832°F), and are expected to keep the data intact for 13.8 billion years at room temperature (anything up to 190°C, or 374°F).
It’s a discovery that “opens a new era of eternal data archiving” because the discs have “virtually unlimited lifetime,” the university says, and museums, national archives, and libraries could benefit from having this eternal storage.
So far, scientists have preserved important documents such as the Universal Declaration of Human Rights (UDHR), Magna Carta, and Kings James Bible on individual discs that will likely survive the human race.
The researchers are now looking for companies to help bring this data storage technology to market. No word on when it might appear or whether it will be available and affordable to ordinary photographers, but perhaps one day we’ll be able to store our entire lifetime body of photos on a single disc that is guaranteed to survive us (and all our descendants).
