    Hi all :)

    I was wondering: is there any reason not to use ext2 on an USB
pendrive? Really my question is not only about USB pendrives, but any
device whose storage is flash based. Let's assume that the device has a
good quality flash memory with wear leveling and the like...

    Thanks a lot in advance :)

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?
