I'm a bit surprised BluRay is not mentioned. It's relatively cheap cold archival storage. Of course the recovery latency is a bit bad because of manual steps, but hey, why not repurpose that old jukebox you have in the garage ;)

the article is about quasi-infinite aka "archival" storage. not decades.

  M-Disk blurays are supposed to last a long time

    no, only the DVD-R last a long time. the BD-R aren't rated https://news.ycombinator.com/item?id=40240126 https://news.ycombinator.com/item?id=40240126 see other comments in that thread (rooted at parent https://news.ycombinator.com/item?id=40237984 https://news.ycombinator.com/item?id=40237984 ) i can't find an original source but for sure back in that era i read info that the BD-R is not rated. as a data hoarder i ended up not going with that tech due to that analysis. even the main m-disc site only says the BD is "based on" the same tech, not that it was also evaluated. all i can find right now is overwhelmed by marketing and bloggers repeating the not-well-supported 1000 year claim for the BD. anyway, from a bit of googling it appears you can't buy BD version of MDisc any more anyway. The ones marketed as such are apparently the more "normal" HTL BDR which are good for 100 years. https://www.reddit.com/r/DataHoarder/comments/1alz63y/real_mdisc_is_either_47gb_dvdr_or_25gb_bdr_all/ https://www.reddit.com/r/DataHoarder/comments/1alz63y/real_m... seems to be a good analysis, supporting the thought that it's likely only the DVDR that ever met the 1000 year claim.
