This wiki page is a collection of ideas for Project Valhalla.

<SketchCow> Basically, we have this situation where we have stuff that is being threatened,
and it's huge, and then it's either not so threatened or it's in a weird quantum state.
So, this really stretches the bounds of what IA does. It's a huge amount of data, it's not likely 
to be overly touched if the originals are up, and IA will spend/lose a lot of money pulling it into their infrastructure.
So maybe we can discuss actual, not pie-in-the-sky possibilities of what we can do to have some sort of not-IA pile of storage.

Options

  • Hard drives
    • These would have to be live. HDDs decay quickly, and if they're not spinning, you can't detect failures.
  • Commercial/archival-grade tapes
  • Consumer tape systems (VHS, Betamax, cassette tapes, ...)
  • Vinyl
  • PaperBack
  • Optar
  • Blu-ray: lasts a LOT longer than CD/DVD but should not be assumed to last more than a decade
  • M-DISC: Unproven technology, but potentially interesting.
  • Flash media
    • Wears out quickly, not-so-good long term storage
    • Soliciting donations for old flash media from people, or sponsorship from flash companies?
  • Glass/metal etching

Non-options

  • Ink-based Consumer Optical Media (CDs, DVD, etc.)
    • Differences between Blu-Ray and DVD? DVDs do not last very long.
  • BitTorrent Sync
    • Proprietary (currently), so not a good idea to use as an archival format/platform
  • Amazon Glacier
    • Amazon Glacier seems like a a great idea, until you realize they mean 1 cent per gigabyte per month. This is $120 per terabyte per year. The transfer out of 100TB would also run over $10,000 the month its pulled from the system.
  • Floppies
    • "Because 1.4 trillion floppies exists less than 700 billion floppies. HYPOTHETICALLY, if you set twenty stacks side by side, figure a quarter centimeter per floppy thickness, excluded the size of the drive needed to read the floppies you would still need a structure 175,000 ft. high to house them.
