The Impact of Disk Fragmentation
While there is little dispute among IT professionals regarding the impact of disk fragmentation on system performance, no independent guidelines exist to recommend the frequency of defragmentation across an infrastructure. While just about every IT professional has his or her fragmentation horror story, very few can offer more than anecdotal evidence regarding the use and importance of defragmentation software.
This white paper outlines the results of testing carried out by the author, addressing the impact of fragmentation on user and system activities, and how quickly fragmentation accumulates as a result of these activities. The paper draws conclusions based on the testing and makes recommendations in regard to managing fragmentation across an infrastructure.
