As I understand it!!! [I.E. I may be wrong, in which case I'm sure
someone else will chime in.]
HFS+ is Apple's standard file system for the recent past.
HFS+, Journaled, is HFS+ with the 'Write' operation 'enhanced' by
first writing out information as to what the write is going to do. So
that, if the 'write operation' is interrupted, the SYSTEM can go back
and Re-Do the missing steps to recover. The 'Journaled' version HAS
to be slower, because of the extra steps involved, but it provides
another level of 'data security'.
My own decision so far --- Hard Drives ---> Journaled
Jump drives, Thumb Drives etc.---> HFS+ ONLY, less
writing/ re-writing =less activity using up the finite operation
cycles of the 'flash memory'.
