Possibly other archival grade CD's/DVD's, such as the 'J-DPR-ZZ-SB16' discs?ĭiscs that are NOT archival grade and have an organic layer include: M-discs (DVD's, however they have low capacity and high cost): 4.77gb per disc.īluray/Bluray M-discs (I haven't seen any difference in material nor spec for M-disc vs regular Bluray): 25/50gb per disc.īluray XL/Ultra HD/4K: these are about 50/100/125gb per disc.Īrchival Disc from Sony (example: ) - Way too expensive for me at this moment. As far as I know, there's a few long-term archival solutions in terms of optical media: However, since there's so many confounding arguments and facts on the optical media topic, I thought to maybe discuss this with this post. While yes, original CD's and DVD's contain an organic layer that easily rots, there's better solutions out there.

Now as already mentioned in the title, I think optical media could actually offer a solution here.

HDDs have an average lifespan between 3-5 years, SSD suffer from extensive bitrot, Tape needs heavily controlled climate solutions, with both tape and HDDs having magnetic degredation over time. I have come to a point where my personal collection is getting somewhat extensive that I need long-term archival solutions that can be left on the shelf without being touched.
