have seen as high as 7.

they seem to get faster the further along it goes.

look into using AUSLOGICS degragger instead.

faster and also has an option to move system files to the front.

    Mine's been running and it's doing it's 8th pass in 14 hours with no sign of stopping. Obviously, a larger hard drive causes it to take longer.

    windows 8?  not enough time to fragment a drive so recent... you have to understand that sorting algorithms aren't that smart, and defrag is a process with diminishing returns, you can choose to sort everything until its perfect, taking 10 times as long to gain 000.1% more in performance, the truth is you let it finish if you want or have time, else it really doesn't matter.

    mine is 500gb hdd and fragmentation is around 6%gb of where 400gb+ is already used..just thankful its finish now..it took me around 8 hours to finish defragmenting it in different times by recontinuing the process since it takes too long, i think it took around 20-25 passes..whew

    yep well assuming even 40mb/s continuous read alone 500gb would take 3.5hours just to read it all if i didn't screw up the simple math. and of course its read write and small bits aka "fragmented" so even worse, and no sorting algorithm is that clever so going in passes is going to be the way to do it, making it even slower.  so even if it hits the drives more likely max read speed of maybe double that, it will take a while...

    in win vista/7 you can look at what files the drives are reading and writing and how fast in task managers performance manager section, then you can get a good idea of the true speeds its working at.
