Well, you can always get archival M-DISC. https://www.mdisc.com/
Treated special materials to resist moisture and UV degradation. Should last 1000 years if not tampered with and stored properly. Idk what the read/write speeds are, but they offer a 100GB bluray disc option. You will be long, LONG gone before the storage is no longer intact. Obviously not “forever”, but pretty close to it practically speaking on human lifetime scale.
I mean, you could engrave onto stone and expect that to last pretty much forever if stored correctly. The read/write speed and storage capacity leave a lot to be desired though.
It depends on the conditions. At the end of they DAT it will fail at some point.
