I use Defraggler by Piriform (the CCleaner people) which is extremely quick.
It's still in Beta but I've had no problems at all.  

As well with a very interisting defrag option "On next boot" which is very fast ...

I currently use a free version of O&O Defrag. I like it, seems fast and it give options for defraging that I haven't seen in other programs.

Of course just about any of them will have some special features. Considering getting the paid version of O&O and also trying Defraggler.

Just an opinion, fast can be relative to the size of the HDD, defragmented files and available free space on the drive. I know I have read that somewhere, I'm not smart enough to know that by myself.   

I tried several defraggers and came to the conclusion that PerfectDisk is the fastest. It's not very fast--it usually takes 4-5 hours for a complete defrag, so I tend to run it overnight, but I've left other defraggers going for upwards of 8-10 hours before.

mstDefrag. It works in the background so I never have to defrag. You can't get any quicker than zero!

At 4 hours it would seem it had'nt been defragged in a while,even if you reformat install windows & get the updates it will require a fair bit of defragging ,regardless if you use a 3rd party software it will still use the windows defrag engine to achieve it's goal,me personally i defrag sometimes daily or whenever the mood takes me,if it's bad i'll let it run overnight in safemode & just use the original windows defrag to do it,if you setup a routine there's no need to spend money unless your downloading,installing & deleting (amongst other things) gawd knows how many programs in a day & it would be handy to degfrag on the fly etc,if you keep on top of it the defrag won't take long.

ps: before defragging make sure the hybernation option is unchecked & set pagefile to 0 (the two green strips in analyse is what the afore mentioned are & cannot be defragged) unless removed)then boot to safe mode & defrag, once defrag is complete reset pagefile to custom size & set it at one size in the min & max this will avoid unnecessary fragmentation

So your saying the prog you use can defrag any amount of fragmentation in 30 mins pfffft me thinks a few minor details are missing sonny

PerfectDisk 2008 is the best defragger out there. Check out the poll over at Neowin and you'll find it is - by far - the most popular defrag utility with the members there. Try the free 30 day trial and you'll see a very noticeable difference in speed and responsiveness of your machine   

I have used PerfectDisk for some time in different versions it's fast & does the job!

As I said way up there ^^^^^^^^^^ it's all going to depend on what is actually on your system...including defrag frequency and disk size.

Here's a trick.....do a file-count on your C drive.....it'll help demonstrate the [likely] complexity of what's installed.....my C drive has 116,496 of them.....29.6gig of 60...

As Jafo said, there are quite a bit of variables to each system. Personally, Windows Defrag will suit your needs just fine provided that you exercise proper maintenance schedules. The first time defrag will take a long time. Run it overnight. From then on, perform a weekly defrag and you will not suffer long waiting times under NORMAL usage circumstances. It's still best to perform these on a scheduled basis during non-use hours though.
