So the purpose of defragmentation is to revert the process. As a result, different parts of the same files are now separate, and this causes fragmentation.Īnd this is unavoidable since we store and delete files every day.

If you save large files in less free space, your system will save the files in the nearest available space. A cluster is the smallest unit of space on a hard drive that a file or part of a file can be stored in. The second reason is that each unit of space on a hard drive comprises a certain number of sectors. So, why is this important? There are two main reasons.įirst, the data stored on the outer tracks and sectors are accessed faster than on the inner tracks and sectors. The number of tracks and sectors varies by model, but a single sector is usually 512 bytes in size. Each disk is called a track, and each track is divided into portions of similar length called sectors. Let’s say four disks collectively make up the platter. Think of the spinning platter as a composite disk of several concentric disks.

To further slow things down, not all the data that needs to be retrieved will always be in the exact location. These moving parts mean there is a limit to how fast requests the processor sends can retrieve the necessary data. Related : SSD vs HDD: What’s the Difference and What to Choose? It consists of moving parts like the spinning platters and the read-write head. Despite the constant improvements in speed and size, one simple fact about the hard disk drive (HDD) remains – it’s slow.
