Journalling is a great idea. That said, I have disabled it for my video capture (and multi-angle playback) disks. Other than that, I let it do its thing. Video capture needs speed. Voice recognition probably doesn't. You should probably turn journalling on. -- Very old woody beets will never cook tender. -- Fannie Farmer

I suppose a system with many large files is less prone to losing data, but you are right, documentation doesn't help much in making a decision. Maybe you should voice your question to Apple but, in general, people turn journaling on. I don't believe you will feel such a performance hit. Anyways, according to this document: <http://support.apple.com/kb/TA21053?viewlocale=en_US> turming journaling off after it has been enabled doesn't seem like much of a problem.

A hobby user that consistently handles files of 100GB and more! I saw a terrible film a few weeks back where this American farmer built his own space rocket and went off into space, he was always having trouble convincing his bank manager... -- dorayme

That is what I did, and in true Mac pseudo-speak, " I never looked back " - - - whatever the heck that means. Mark-

You should probably turn journalling on. Ha - - - SR is all about speed, when I use a slower Mac like one of the modern Mac Minis, all the benefits of Speech Recognition vaporize in a puff of smoke. When I rattle off dictation like this, the poor Mac Mini grunts and groans, glowing a dull red from heat, so I am forced to slow down my dictation to 60 wpm. "Two pairs of 5-0 and 4-0 Gore-Tex sutures (W. L. Gore & Associates, Flagstaff, AZ) were each placed to both fibrous portions of the anterior and posterior papillary muscle tips, buttressed with pledgets of autologous pericardium." Heck, any half-ways competent typist could do that, why would anyone need expensive SR gear to keep their medical records? Software to fill out EMR forms, from "MacPractice MD" alone runs $5,000 - - - and that is on top of the $1,600 for Dragon, not to mention the $600 for an Olympus DS-5000 shirt-pocket digital recorder, or the $300 wireless "Airline 77" mic', or the ... You get the idea, plus the doctor has to pay all the IT guys to keep all this software/hardware running. By contrast, with a newer faster MacBook Pro with 8 GB of ram, 512 GB solid-state internal drive, I can easily double my dictation rate to double that, namely 120 wpm, _provided_ I crank up its fan speed manually to 6,000 rpm to keep it from melting. That makes a helluva difference to the doctor, who would otherwise waste two hours after his shift typing in Obama-required paperwork, while his marriage suffers, he becomes an alcoholic and a doper, and the ambulance chasing legal beagles plot multi-million dollar lawsuits against him, because he is so bombed from lack of sleep that he makes medical mistakes. But I digressed, didn't I, what does all my tirade have to do with our toy computers and the Apple Music Company. Nothing, I apologize, <sob> Forgive me, if you can. Mark- |
