Journaled or un Journaled
Hopefully somebody is up a chewing their cud at this time of night. I’m about to strip a 4 disk e-sata raid. Has the argument ever been really settled about extended journaled or un journaled I know that Apple says to format them Journaled, but some of the more influential members of the herd say no…. anybody with quick thoughts on this.

Yes, many many times on this very forum.
Main System Harddrive – Journaled.
Media Drives – NOT Journaled.

Oh crap. Both my Raids are Journaled! They’ve been like that for quite a while with no issues. Dare I ask what the issue is with Journaling?

Hi Ernie,
I don’t know about RAIDS, but in general, Journalling ads an extra data control system for the HD. An extra checking system to fix the position and integrity of the files, or so.
In HDs with many files (like a System HD) it’s helps to keep track of the files.
It’s ads an extra step in the process of managing the data of any HD, so it would add an extra time to access that data.
The Systems HD must be always Journaled (no way to install if not). They contents hundred of thousands of files.
For the media HDs journaling doesn’t helps much and could make the editing slower. So, disable.
There are applications that lets you disable the Journaling without reformating the HDs.
However if you are happy with the speed of your system and raid, why to touch it?Mac OX 10.5.2-FC 6.02-QT 7.4.1

Can you please tell me what the application is that you refer to which disables journaling without having to reformat?

I have to say that the Apple team recommendation when this first came up was to journal all your drives. I don’t believe the minute amount of time journaling adds to accessing a media file has any real affect on drive performance. I don’t think it’s even measurable.
All the best,

Not sure because I’m on my laptop right now, but doesn’t Disk Utility (built right in to the OS) now have a button for Journaling Unjournaling?
BTW, my suggestion is, enable jounaling on *all* drives, unless the (slight) performance hit
is too much (meaning, if you’re a bleeding edge, fill my RAID to the max, “I only do 1080P with 5 video streams” kind of person). 🙂

Thanks for the info on Journaling. I will re-configure my drives at the next break I get between projects and revisions.

Ernie, i wouldn’t worry about it. Seriously. The benefits of journaling greatly outweigh not journaling. You will hear all types of different theories, so here’s mine. Journaling is great for recovering from crashes. That’s what it’s there for. Your drives will not take a hit.
My raid is journaled and it clocked in at around 475MB/sec the other day at around half full. You have nothing to worry about.
