But the guaranteed lifetime of the data is not stated!
I stand by what I said: the only REALLY PERMANENT data storage devices
with no moving parts were the fusible link PROMs. AFAIK none of them has
ever "faded" even after several decades.
Of the moving parts systems, the most permanent medium is punched paper
tape or card. This has been shown to store data 100% intact for over 100
years.
Go placidly amid the noise and haste,
and remember what peace there may be in silence.
