I have floppies from the 1980s that are still readable, but I have
never had a USB flash drive last more than six months when actually in
use.  For important data, I trust a floppy far more than I trust a
flash drive. The big problem with floppies is they don't hold enough
data. For that matter, writeable CDs and DVDs have proven to be much
less reliable than floppies, too.
