    No, there is no need to, as the Mac OS Extended file system (HFS+) takes care of this in most cases. I never needed to defrag my HDDs with Mac OS X.

    Articles explaining why Mac OS X does not need maintenance software like CCleaner, MacKeeper or CleanMyMac:

    With very few exceptions, you don't need to defrag on Mac OS X, except possibly when partitioning a drive.

    Actually, if you do work with large files defragmentation can be beneficial.

    Not because HFS+ automatically defragments small files, because HDD speed gets significantly worse as the drive fills up. Having files stored in the slower parts of the drive will inherently drop the speed for almost 50% (in mb/s) and hinder access time.

    Also, you don't defrag SSDs as there's no benefit and it just reduces the life of the drive. Modern OSs like Win 7 and hopefully OS X know not to automatically do it.

    I certainly hope so too...
