Comment on Twenty percent of hard drives used for long-term music storage in the 90s have failed
mark3748@sh.itjust.works 1 month agoPressed optical disks, yes. Dye-based writable and re-writable do not last very long at all.
Depending on the disc, they can last anywhere from 5 to over 100 years. The over 100 year ones are (were?) marketed as archival, and only CD-R. Do not trust any random writable disc to survive very long.
I tested some backup DVDs from 2012 a couple of months ago and they were completely unreadable.
