Your USB pendrive will wear faster if you use an inappropriate
filesystem. Such filesystems require frequent writes and change their
internal state often.
This could be alleviated by COWing the filesystem somehow and flushing
writes when you're finished. But the modifications will be lost if
crashes occur. The filesystem structures will still change a lot and
require big writes to update it.
Really, why don't you try a more suitable fs for your pendrive, one that
changes itself less than usual fs's?
