I wonder if there is a better printing technology comparable to analog "prints" (of film). That would actually make more sense (to me) than saving everything on M-Disc.
This is an _additional_ layer of backups, on top of the usual iCloud/whatever things. LTO is certainly not user-friendly, but neither is it especially user-hostile.
And I think I trust tapes far better than any other alternative for long-term storage as they have by far the smallest areal density of information compared to disks (hard or optical).
I have DVD disks that are barely 10 years old and that I can't read anymore. Hard drives also die in storage and/or during transport.
Recently the computer museum helped recover early 1970s unix tapes. It was a big deal.
And let's not exaggerate the complexity of setting up external tape drives, even on Windows/macOS.
Having found a matching Sun Ultra 5 generation drive, I tried to get it to work with a SCSI card, and had .. many many problems. It may be the rubber bands. It may be stiction. it may be ants. It may be me.
I would personally love to de-exaggerate the complexitity: Old hardware is gnarly. I sourced parts, it wasn't working.
And yeah, I started with a ZX-Spectrum with cassette tapes. I was pleasantly surprised by the overall LTO experience.
