OTOH if the platters ARE turning, what's to prevent bleed? Unless you
mean over a period of decades....

Do you mean the ubiquitous "memory sticks"? But how long can they store
data without errors?

The only "no moving parts" devices I know that really were permanent
were the fusible link PROMs, but they were mostly limited to less than 1
Kb of data.

UV-EPROMs rarely lasted more than about 10 years, EEPROMs somewhat less.
I don't know what technology the memory sticks use, but I doubt that
they would last for more than a few years unless stored in a specially
cool environment.
