Since you are likely not using data journaling (if you had a mail spool you might) then you do not really need much journal space. The large file sizes means that you will not really get much benefit from the external journals at all, since the majority of the I/O is going to data blocks. The only real activity will be mtime updates and the occasional file create. As with anything, do a performance test with & without the external journal. If the external journal doesn't give you any benefit then stick with the internal journal, as it is less admisitrative effort and much better tested (more widely used).
