Best Answer
A journaling filesystem records changes to the filesystem before it actually performs them. In this way it is able to recover after a failure (e.g. power fail) with minimal loss of data.
The Features section of Wikipedia's comparison of filesystems gives which are journaled.
Journaling does not give a performance boost. In fact, the journaling operationn reduces the speed slightly, in exchange for the above reliability.
