when you need long term stable storage without getting hit by bit rot

  Pretty sure it's not immune to bit rot. Have any data to back your claim?

    Tape drives will, when writing, re-read the data as it is written to make sure no errors are written and will transparently correct any errors. In addition, quite a bit of error correcting code is written, making it possible to correct simple errors. So perhaps not 100% immune, but partial immunity to bit-rot is a pretty important part of the LTO spec.

    Immune, no. Far less prone to bit rot? yeah. My source is running backups for a significant fraction of a large univiersity for ~20 years. We had a routine cadence of tape errors, which were much less frequent than our routine cadence of disk replacement. I suppose that's anecdote. :) But it's what I've got.

      So 30 years for HPE when stored in appropriate himidity/temperature range.
