Common Countermeasures
- Partitioning
A common strategy to optimize defragmentation and to reduce the impact of fragmentation is to partition the hard disk(s) in a way that separates partitions of the file system that experience many more reads than writes from the more volatile zones where files are created and deleted frequently. The directories that contain the users' profiles are modified constantly (especially with the Temp directory and web browser cache creating thousands of files that are deleted in a few days). If files from user profiles are held on a dedicated partition (as is commonly done on UNIX systems), the defragmenter runs better since it does not need to deal with all the static files from other directories. For partitions with relatively little write activity, defragmentation performance greatly improves after the first defragmentation, since the defragmenter will need to defragment only a small number of new files in the future.

Famous quotes containing the word common:
“There is all the poetry in the world in a name. It is a poem which the mass of men hear and read. What is poetry in the common sense, but a hearing of such jingling names? I want nothing better than a good word. The name of a thing may easily be more than the thing itself to me.”
—Henry David Thoreau (1817–1862)
