ext3 seems like overkill on a thumbdrive, you are probably better off
with ext2 (no journal). The usage pattern on a thumbdrive seldom
justifies the use of a journal.
The lowest overhead of all is vfat, especially if it's just a bunch of
data files you are storing and have no pressing need for file
If only you and dead people understand hex,
how many people understand hex?
