I think that it depends on the type of journaling: journaling metadata only doesn't protect your files which can be corrupted, but among other ext3fs has a journaling data+metadata, which has a quite high performance impact, but it should 'protect' as in the data is here or not here but it isn't half here (seen with ReiserFSv3: the passwd file appended with binary data, urgh).
Of course even journaling 'data+metadata' can work correctly only if the disk obey some order of writing the data.
