    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 :)

My opinion is that, unless the flash is really cheap, or it is being written to excessively, that it probably doesn't matter too much. With the growth in size of flash, just how long do you think it will continue to be used before you go to something larger?

A 256MB flash of a few years ago has been supplanted in many cases by today's 2-4gb memory.

One suggestion with ext2 might be to mount it with the noatime option, so it doesn't update the last access time for directories and files. Otherwise, you are doing a write even when you only plan to read a file.
