Comment on Twenty percent of hard drives used for long-term music storage in the 90s have failed
Gucci_Minh@hexbear.net 1 month agoOptical discs like CDs and DVDs last a very long time if stored properly. It’s using them that kills them fast. So in terms of data archival they’re actually pretty good. Regardless, u right, make backups of backups and replace the media its stored on every once in a while.
Pressed 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.

Yeah I work for a place that uses discs for archival in addition to tapes and the discs do have specific requirements for storage, like opaque boxes in a temp and humidity controlled room. The discs are also some fancy Japanese brand I’ve never heard of. Probably best not to pickup a pack of CD-R at the walmart and use those.

i’ve had factory printed DVDs die while stored at room temperature in the dark (case). they just developed holes.
