Disk Defrag Software for Mac OSX?

Only free stuff for macs I could find are:

If you come from the Windows user community, you must think your Mac will perk up if you defrag the drive. This is almost never needed on any Mac with one exception: Final Cut Pro for editing movies (a cool thousand bucks if you didn't get it free like I did while working for Apple) may show some improved performace on IDE drives if they are defragged occassionally. SCSI drives are better optimized for video so they may never need defragging. Finding a SCSI drive larger than 72 GB is a bit of a chore, however.

I once had Norton Tools that included a defrag tool for Mac OS9 and older but I haven't used it in years because it did not change any parameter of performance and took too long.

If you actually have some reduced performance on a Mac in normal daily use, it is unlikely to be related to fragmentation. Look elsewhere for the answer.

In Mac OS X, you don't need a Disk Defrag, but you can optimize your system by using either System Optimizer X or Xupport.

Hope this helps.
