When the physical memory required by the application is insufficient, the operating system will generate a temporary disk swap file on the hard disk, and use the hard disk space occupied by the file to virtualize it into memory. As time goes on, files are scattered and stored in different places on the entire disk, rather than being contiguously stored in continuous clusters of the disk. Only the new hard disk may store files continuously for the first time.
Traditional mechanical hard disks use magnetic disks to store information and read them with reading/write heads. In this part we’ll show all details about disk defragment and how does it improve the performance of a hard drive.
What is a disk defrag operation? Will that hurt my hard disk? Can it speed up my hard disk?.
