Public Service info from the volunteer chief archivist at datamuseum.dk:
NEVER use flash-based storage for archival purposes.
Not CF, not SD, not USB-sticks, not SSD, not NVME, nor any other flash-technology based storage media.
Flash is simply not a stable storage mechanism: Just like Dynamic RAM it will eventually forget your bits.
Unfortunately there are no good choices for long term data storage, but flash is a particular bad choice.

@larsbrinkhoff @bsdphk @jonathan @cstross care to elaborate? All I heard is that it is the "best" option.
@larsbrinkhoff @ekg @jonathan @cstross
In datamuseum.dk we have approx 80% luck with ½" tapes, and very very bad luck with ¼" cartridges.
Also troublesome: Hard disks from 1990 forward.
@ekg @bsdphk @jonathan @cstross Lots of tapes written long ago are hard to read today. Often they flake apart, so you only get one chance of recovery.
