That is the difference in fact - Ilgaz

This tool,when set "Full defrag" actually does "optimize". It changes the whole disk layout so lets say OS X loads frameworks while it boots, they will be near eachother so it will be really faster. It can't be matched by "defragment" utilities. It does the usual "defrag" without requiring system booted from another partition, it is named "Quick (Online)"

Another difference is, this Application has zero tolerance against failure so that is why you don't even see "Shutdown when done" option. They want user to make sure the disk is all fine before shutting it down.

Or, it could do lots of stuff in memory while it actually moves every data on disk. It is like V-Opt (a very trustable util) for Windows. It moves, makes sure data is excellently intact (verifies) and deletes (frees) the original, updates the journal (others disable journal).

As there is no "virtual" stuff around, even if your system fails horribly, data is safe.

(I am just a user knowing how defrag/optimise works)

If it's that slow, you might... - hoezone156

...concider more memory for one. You never mentioned your rig, that has alot to do with the speed of iDefrag as it would with any utilities you'd run.

I'm running a G5 Dual 2.5 with 4GB of memory, and a full defrag on a 350GB SATA drive takes around 2 hours or so. I'm using 3 drives, and simply reboot to a different startup disk. It's the best defrag utility I've seen out there for Mac users.

(I am wondering what changes were made in this latest update though)
