Optical media is unmatched for archival purposes. I have photos, videos, and documents I'd be devastated to lose. I simply cannot trust magnetic or solid-state storage over the long term.
Luckily blurays are still somewhat cheap in Japan so I stock up when I visit. Stored properly they should outlive me.
- toast0 1y agoIf you care about your data, you need to have a regular process where you check the copies and remake them from time to time. Hopefully some of the copies live on after your death. Optical does well, but I've seen reasonably treated cd-rs degrade, and well treated pressed cds decay. Sometimes some mistake in production takes years to become apparent, but results in a fixed lifetime below the estimates.
