Enterprise is moving away from tape to optical for archival (or so I've heard). It is rumered that AWS S3 glacier is mostly optical storage, for example.

  > It is rumered that AWS S3 glacier is mostly optical storage, for example. Really? I heard that about a decade ago, the analysis barely made sense then but it seems even less sensible now. At Amazon scale tape is 0.5 cent/GB or less, hard drives are more expensive but easier to work with. Data storage on Blu-ray is tiny, still needs robotics.

    >hard drives are more expensive but easier to work with But maintenance is much lower for optical. You can't just put those hard drives in a warehouse and forget about them. And BDXL is 100GB per disk. I don't know if the cost benefit makes sense here but it does seem somewhat possible.

  Most optical archive products seem to have been discontinued.
