I think it could benefit performance putting a journal on a faster RAID 1 
mirror if you have a huge RAID5 array. Remember that if you have one of
those expensive RAID controllers with battery-backed write-back cache,
you should have the FS synced so that you have the speed-up
of the write-back cache AND data consistency guarantee in a crash. softupdates
alone guarantee metadata consistency in a crash only. You still lose
data.
