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.
