    From the thumbnail, I expected: Scientists develop world’s thinnest waffle.

    Anyone else convinced AES-256 is not long enough a but length for full disk encryption anymore? Even the 512-bit schemes are just trying some offset-salts that, with ~10TB I worry about providing close-enough statistical significance for cryptanalysis.

    With 100TB drives?! I am less worried and more… convinced its a problem.

      I have to admit, that I never looked into the technical details of full disk encryption

      If I understand you correctly, they are using the same key for all the data and with larger amounts of data statistical analysis becomes feasible
      Did I get this right?

      Couldn’t that be solved by using a root key + salt per block/sector/file/whatever?

      I’d still only need the one root key and with every block the actual encryption key changes

      I was thinking about perfect forward secrecy and that was the first thing, I could come up with

      But, I’m absolutely not a crypto/math guy, so probably I don’t know enough to really add something to the discussion/solution…

      I assume this is not something I need to worry about with 1TB drives at all? That’s a pretty cool fact about cryptography/data storage I did not know, thanks for sharing

    If I had been the project leader on this it would have had an even greater capacity because I would have taped a couple of keyring flash drives around the edge.

    I remeber times where a 51/4 cardboard floppy was enough for all my documents and apps.

      51/4 cardboard floppy

      Wait, I’m also old enough to remember 5.25" floppies, but I always thought the casings were some sort of flexible plastic. Were some of them just card stock, or were they all some sort of treated paper product?

        I know these as cardboard case, but certainly with some treatment to make it more resistant.
