If you have enough trust in your El Cheapo hardware supplier. There
is no standard that requires wear leveling and there are reports that
basically tell you to do your own wear leveling on some devices. With
no good way to distinguish "some" devices from "others", you can read
that as "all". ;)
USB keys and all the various other consumer-type flash devices are
good enough to beat 3 1/2" floppies, that's about it. But that's
quite good enough for most people. Floppies sold like crazy after
all.
