Yes, that and eliminating the journal reduces the number of times the disk gets 'hit'.
Exactly. That's the point of the exercise.
But from an integrity POV removing the journal on a production device worries me. The reference you give for the USB stick, well, yes, OK.
I am not 100% certain of this, but in my fairly limited experience of Flash device failure, the failure mode is significantly different from that of spinning HDs. HDs degrade slowly and blocks can become unreadable or writable. A journal can help you to survive this. Flash devices tend to fail suddenly and completely and journalling is no help -- everything is gone. So I have an unsubstantiated suspicion that in real life a journalling FS won't help you with a failing SSD, but the existence of the journal may bring about that failure quicker. -- Liam Proven - Technical Writer, SUSE Linux s.r.o.
