M-Disc is a digital optical medium for archival storage. Not indestructible but more resilient to degradation than the typical BD/DVD-R.

  All BD-R use the same inorganic recording as M-disc. It's only worthwhile for DVD and CDROM.

    Are you suggesting blueray will last as long as M-disc?

    I'm not sure that's true. I would love it if so! https://www.canada.ca/en/conservation-institute/services/conservation-preservation-publications/canadian-conservation-institute-notes/longevity-recordable-cds-dvds.html https://www.canada.ca/en/conservation-institute/services/con... Just one article discussing it. Do you have a source to back this up? M-DISCs are getting hard to purchase these days, and I have a lot of stuff I want to put on them which I likely will want to look at in 30 years.

    Mdisc uses a special very hardened layer thats set it apart from other discs. That is why long term storage works so well. "Instead, the M-DISC™’s data layer is composed of rock-like materials known to last for centuries. The M-DISC READY™ Drive etches the M-DISC™’s rock-like layer creating a permanent physical data record that is immune to data rot. The stability and longevity of the M-Disc DVD has been proven in rigorous tests conducted according to the ISO/IEC 10995 test standard for determining data lifetime of optical media." https://www.mdisc.com/faq.html https://www.mdisc.com/faq.html
