Read the following article by Executive Software, maker of "Diskeeper":
It is a common misconception that a defragmented disk should look
very neat and tidy in the analysis screen, with solid blue bars all the way
across the screen (representing fragmentation-free files) and the rest
white space (representing consolidated space).
Clearly, the speed of the disk, meaning how fast you can access the data
on it, is more important than the prettiness of the display or the consolidation
of all the free space into one place. Free space consolidation might be
important if you have to create one gigantic contiguous file, but it has no
effect on performance. So Diskeeper uses algorithms that achieve the highest
speed from your drive regardless of the arrangement of the free spaces on the
drive and on the screen. And it does so without wasting time on excessive
consolidation of free space. We simply go for the fastest possible file access
times and then stop.
Even so, you might ask why we don't continue and rearrange the files further
to get a neat display? The answer is, "Because it takes computer power to do
so." We long ago decided that it would be wrong to consume more of your
computer's performance than we give back. So Diskeeper defragments until
the disk is in top shape PERFORMANCE-wise and then stops. Any further
work is a waste of your computer resources.
Now this might not be a big deal if you like to watch the display as Diskeeper
defragments your drive, but it is a very big deal to people who depend on their
computers for their work. They need all the performance they can get and can't
hold up production while the defragmenter pretties up the disk. This is why Diskeeper
is designed to run in the background at the lowest possible priority, giving way to any
other program that needs to run. And it is also why Diskeeper STOPS defragmenting
when maximum performance has been achieved.
