Ultimate backup solution. Will not die like HDD, will not vanish/locked-out like Cloud.
Use it for precious data, not Linux ISOs. I recommend Verbatim USB Blu-ray writers, 43887, 43888, 43889 $157 and the like. Pioneers will do too, look for "M-Disk" or BDXL support, check by downloading user manual. Buy two and keep one with the written disks offsite.
Looks like lowest per disk at the moment. Non-organic chemistry in BD-Rs 50G and above - will not go sour in 100 years.
Specs (5th image on Amazon listing):
- It is suitable for long-term storage by adopting a unique MABL recording layer.
- Protects from damage by adopting a strong surface protective layer
M-Disk or not?
Likely not, but still 100 years guarantee for MABL recording chemistry, see here and here.
M-Disks claim 1000 years. M-Disk surface looks more golden, this is probably will be dark blue.
Must have player that can play them…. hope that works in 30 years from now
