    No, Mac does not need to be defragmented.

    I'm no authority, but when I did a full defrag with this software iDefrag, my Macs were noticeably faster. I don't know how it is, but it is.

    Same here.

    Don't believe rhetoric of a company trying to sell you something. Even OSX needs manual defragmentation every now and then.

    DiskWarrior's optimized directory also gives a noticeable boost.

    No offense, but I'll go with the guys who engineered the filesystem on this.

    or perhaps some other guy who's actually looked into fragmentation on HFS+

    No, it usually doesn't, but if if it makes you feel better, go for it.

    I'm telling you man. It does speed up. The full defragmenting puts all the applications at the start of the disk and does all that defragmenting which we see on PCs. My one year old iMac was running like a mad dog after doing a defrag and so was my iBook...

    DiskWarrior appears to be a $99 package. That is a LOT of money for a utility whose speed up benefits appear to be in some question.

    I would invite others who have DiskWarrior to comment. Do you observe a noticeable speed boost after running it? Are you also running other maintenance at the same time (such as OnyX)? Are you sure that the speedup comes from DiskWarrior and not other activities?

    DiskWarrior is mostly useful as a disk repair and data recovery tool. It's optimization features are of little use to most people, but that doesn't mean it's not useful.

    Maybe it did, but it's like those "I lost 80 pounds in a week!" plans..."Results not typical." I would not suggest disk optimization on an HFS+ disk as a matter of course.

    Mac Pro, 8GB o' RAM, 4.5 TB o' disc space, OS Ecks 10.6.7, etc
    What does Disk Warrior do besides optimize the directory? That's the only thing it ever does for me. Granted it has helped problems in the past, but I didn't know that fragmented directory data could be such an issue.
