Many folks have listed their varying needs and reasons for wanting to use
3rd party defragmenters. If you feel that on the fly defragmentation is
necesassary for you, then you will view a 3rd party defragmenter as
necessary.
On the fly defragmentation has not ever been a part of Microsoft's Disk
Defragmenter - that I know of. Vista's defrag, does defragment volumes,
although it doesn't show you pictures, progress bars, etc. Personally I am
really coming to prefer this for myself, but then I live defrag some days.
Vista defragger is slow in large part because of the low priority it uses.
See

for notes on upcoming perf improvements not dealing with low-priority io.
Attached is a screen shot of vista defrag gui on my computer.
If anyone else has been running with Vista Scheduled Defrag "on" for a
little while, I'd love to hear about your stats! Mine are below.
I have been running Vista without reinstalling (upgrades only) since about
August with the automatic schedule. This is my system volume, a partial
printout. For me as a user, my mft info and folder fragmentation isn't
something I often look at. As someone working on defrag I look at it all
the time, but not as a user.
Volume size = 50.00 GB
Cluster size = 4 KB
Used space = 37.63 GB
Free space = 12.37 GB
Percent free space = 24 %
File fragmentation
Percent file fragmentation = 0 %
Total movable files = 118,082
Average file size = 340 KB
Total fragmented files = 170
Total excess fragments = 624
Average fragments per file = 1.00
Total unmovable files = 201
Free space fragmentation
Free space = 12.37 GB
Total free space extent = 16,656
Average free space per extent = 779 KB
Largest free space extent = 1.73 GB
YMMV, but I find that even on Tuesday night, my fragments aren't high. The
files for which fragments are the highest are things like temporary files
and log files.
My other (arguably more active) volume:
Volume size = 41.01 GB
Cluster size = 4 KB
Used space = 31.18 GB
Free space = 9.82 GB
Percent free space = 23 %
File fragmentation
Percent file fragmentation = 0 %
Total movable files = 379,213
Average file size = 152 KB
Total fragmented files = 49
Total excess fragments = 130
Average fragments per file = 1.00
Total unmovable files = 5
Free space fragmentation
Free space = 9.82 GB
Total free space extent = 16,721
Average free space per extent = 616 KB
Largest free space extent = 802 MB
In short, to get good defragmentation, you do not need a 3rd party
defragmenter. To get good information on the current state of your volumes,
you need only open an administrator command prompt and defrag /a /v them.
