Why schedule defrag Windows 11/10 PC?

As long as you choose HDD instead of SSD, you’ll confront the problem of the file fragments. What is fragmentation? How to deal with it? Let’s read more about fragmentation at first.

1. Fragmentation
Due to the working way of traditional hard drives, the discontinuous files will generate in the process of reading and writing.

When you delete files, the space will be released; but if there are new files, they’ll be stored in the space your hard drive released before. Then the new files have to split into pieces to store in the space on the disk, thus, the fragments appear.

Defrag example

If the files are stored continuously, the hard drive only needs to find out the entire file in order to read the file. But if it’s reading a fragmented file, your hard drive needs to find the file in each location where the file is stored. Especially for mechanical hard disks, when the file is continuous, the disk can complete one revolution to read all the data. If the file is not continuous, not only need to rotate the disk a few more times, but even the head that may read the data also needs to move.

Therefore, disk fragmentation will increase the seek time of the hard disk and affect the performance of your devices.

2. Schedule disk defrag
Since the fragmentation will decrease the performance and affect the efficiency of the entire system, defragmentation is important. The process of defragmentation can rearrange the messy files to help the disk work efficiently.

3. Do Windows 11/10 automatically defrag the disk?
In fact, users can manually run the program of defragmentation built-in Windows 11/10 or set a schedule to defrag tasks in that tool to defragment the selected disk regularly. We’ll show all details in the next part.
