I’m wanting to archive some right-wing books in .txt format, cartoons, and music. M-Disc looks like the most reliable choice, and I figured I’d share it here.
I doubt claims that M-Discs are significantly more resistant to physical damage (including from regular use), but they will resist time better than currently available alternatives. An implied M-Disc life of centuries Vs. 2 to 5 years for regular CDs/DVDs. This is because M-Disc’s data layer is physically carved in “rock-like materials” as opposed to the standard, short-lived dye.
M-Discs also cost much more per disc, and the only DVD-burners currently capable of writing on them are made by LG. M-Discs aren’t rewritable, so any errors are permanent, requiring a new disc to correct. I probably will not use many discs, but this is again the best long-term storage option I’m aware of.
M-Disc mentions competitors (likely optical discs using a similar technology) claiming 300-year shelf lives, but no brands are listed. Internet searches bring up nothing.
