Why disk defragment is needed?
Defragment is a process that reduces the amount of defragment in file systems and reorganizes file storage on a hard disk partition. The file fragmentation significantly reduces PC and server performance, especially when intensive I/O operations are taking place. Conversely, file defragmentation can increase performance, as the read head has to move less across the disk to read all file parts. By defragment, you can speed up the computer and improve its performance. Defragment is especially useful before resizing partitions, because after defragment, the resizing is faster and more reliable.
