Disk Defragmentation essays

Disk Defragmentation essays Fast, reliable disk performance is mandatory in todays complex information technology world, because system response and virtual memory performance depend on fast disk I/O. unfortunately, common disk fragmentation leads to significant performance degradation. According to one vendor, 58 percent of any I/O operation is disk seek time. So reducing seek time by defragmenting files can play an important part in increasing application performance. How such an intelligent file placement program works and what does it really speed up windowsNT machines? Computer machines play a major and fundamental role in todays world. Almost all applications and studies require a big chunk of work, if not all, to be done on these machines. Thus improving their operation and performance will result in a better throughput and an important improvement of the work. In fact, when they want to improve the operation of a computer running the windowsNT operating system, most people think of adding RAM (increasing memory) or upgrading to a more powerful processor. Recent research studies prove there is a simpler solution : every so often, do a disk defragmentation. This feature, available on windowsNT systems, can more than triple system responsiveness, according to a study by the independent software testing laboratory NSTL Inc., Conshohoken Pa. Almost all operating systems suffer the consequences of files organization on disks, however very few support such a defragmentation software, mainly because their markets are smaller than windows and less appea ling to software developpers. Actually, just by running such a software, both individuals and corporations can enjoy faster system performance. How can this be interpreted? Files or data existing on a computer are stored on non volatile storage devices called magnetic disks; they are usually fragmented into pieces or fr ...
