That’s where Auslogics Disk Defrag comes in. And that causes your PC to spend a lot of time loading them because the disk arm must move all over the surface.

So whenever you install software or transfer a sizable file to the hard disk, it stores into these hundreds of scattered spaces. And these deleted files are spread across the disk’s surface. Then you delete files to free up storage. What ends up happening is that the disk becomes full. However, this effective method becomes more challenging for the disk as you continue to use the disk. This is a time-saving method of storing information on a hard drive. Since there is no data on the disk, the computer can safely place the application’s files in successive sectors on sequential rings.

For example, let’s say you’re putting a new program on a previously empty disk. That will reduce the amount of time spent moving the arm. Hard Disks Are SlowĬompared to the processing and memory speeds, it takes longer for the arm to move for a sector to spin into position.īecause hard disks are slow, it’s ideal for keeping data on the disk in sequential portions. Then, finally, it moves its arm to the appropriate ring and waits for the desired sector to spin into view before accessing it. Data is Stored in Specific Locations on the DiskĪ small arm on the hard disk moves around from ring to ring. Think of the sector as a single pie slice on a single ring of the disk’s surface, much like the rings of trees. Hard disks store data in chunks (or sectors), and each sector holds a set amount of data storage space (about 512 bytes). There are three key facts you should know about hard disks and why having Auslogics Disk Defrag should be a requirement: 1.
