Remember the days when we use to defrag our disks with Norton SpeedDisk? When was the last time you defragged under Mac OS X? No need to thanks to Mac OS X built-in measures against fragmentation?
Learn more about the topic by reading Amit Singh's "Fragmentation on HFS+ Volumes" on kernelthread.com.
Defragmentation on HFS+ volumes should not be necessary at all, or worthwhile, in most cases because the system seems to do a very good job of avoiding/countering fragmentation.
It is risky to defragment anyway: What if there's a power glitch? What if the system crashes? What if the defragmenting tool has a bug? What if you inadvertently reboot? In some cases, you could make the situation worse by defragmenting.
