Defragmentation utility is one of Windows utilities designed just for that.
Disk Defragmentation
No. Disk caching improves hard-disk performance by anticipating data needs.

Do the Defregment disk
An application called a disk defragmenter is the tool used to achieve this. However one could also specifically match the disk segment layout with the disk rotation speed as one sets up the disk or even build a RAID array to increase access speed.
it ill decrease your hard disk performance
A disk defragmenter.
Disk compression on commonly-accessed files Files on the hard disk are too fragmented The computer has a virus
There are a couple options, getting a faster hard drive, (lower seek time, higher disk speed...), make sure the disk has been "defragmented" recently, and if you really need to get some performance, try disk "striping". That should get you some speed when dealing with larger files.
Sata drives are usually faster.
A computer hard disk or hard drive (fixed disk) is hardware.
Disk defrag rearranges files on your hard drive. Its supposed to help speed up the systems speed for accessing files but with hard drive speeds these days disk defrags dont increase performance by a noticable amount
