    'Five-dimensional' glass discs can store data for up to 13.8 billion years

    Not sure this will be a viable option in my lifetime, but this is the data storage of the future.

    Photographs fade, books rot, and even hard drives eventually fester. When you take the long view, preserving humanity's collective culture isn't a marathon, it's a relay with successive generations passing on information from one slowly-failing storage medium to the next. However, this could change. Scientists from the University of Southampton in the UK have created a new data format that encodes information in tiny nanostructures in glass. A standard-sized disc can store around 360 terabytes of data, with an estimated lifespan of up to 13.8 billion years even at temperatures of 190C. That's as old as the Universe, and more than three times the age of the Earth.

    I'm taking a look at something like that. Anyone have one. Is it worth it. Is it reliable?
    Anyone with experience with High capacity Blue-ray?

    I'm sure it is reliable and will outlast you.

    MDiscs can play back on any DVD or BluRay drive, but I suspect the 100GB ones which are four layers deep can only play back on a select few capable of reading that deep (see their list). The 50GB's will likely be more accessible by more drives since most Bluray can read two layers deep.

    And unlike DVD, Bluray is not a widely adopted standard meaning there won't be piles of still functioning drives 20 years from now. But that will be true of any device selected to archive on. Nothing is permanent, nothing is easy over decades.

    To me though I look at that as the best affordable archiving storage I have seen so far.

    13.8 billion years might be a bit over the top. As I understand it the sun is scheduled to expand into a red giant in only 5 billion years and fry the Earth to a crisp. Do you think anyone will remember to pack the disks before they blast off into the great unknown?

    At least the disc's are small enough to put in your pocket, LOL

    That is indeed impressive, maybe we need to redo Voyager.. https://en.wikipedia.org/wiki/Voyage...spacecraft.jpgThat 13.8 B years has gotta be hard to prove unless one came thru the wormhole @ the BigBang. Did you know glass is a liquid?

    SO, if I put data on one of these disks, and after only 12 billion years it becomes un-readable, can I get my money back?
    P.S.- I do save receipts!

    There will be something in the terms and conditions which will give them a get out clause!

    Well that's a relief, now I can go ahead and set up my long term archive!

    Of course there is still dissent :
    There is no clear answer to the question "Is glass solid or liquid?".

    Not that I understand a word of it. Let the physicists and material scientists duke it out, I am gonna be busy archiving away..
