I've never use iDefrag, but most such utilities move your files around so that there are no file fragments and the free space is in one large chuck (contiguous). Since it reads and rewrites almost all of your files, it can be dangerous. You can damage your data if there happens to be a power outage while it is working or you trip over the power cord. It also stresses your hard drive, so if it has issues already, running a defrag operation can make it fail. Therefore, you should always make a backup before using a utility like this one.
It can also take a very long time to complete with large drives. I have another tool that can defragment hard drives, TechTool Pro, but I never use it for defrag on my newer Mac. My older Mac has a small hard drive, so it tends to have limited free space; I use it there occasionally.
