Naturally, our computer would run much more quickly since a lot of seek time are reduced. However, after defragment hard drive, all pieces of the file will be gathered to one extent so that the head only needs to work in one extent. To be specific, when we are accessing a file which is saved in 2 or more different locations, the head needs to move here and there so as to read all fragments of the file, thus increasing seek time. If a file consists of multiple fragments, the hard disk ( especially magnetic head of the disk) will do much extra work. Decrease Data Access Time Largely (speed up computer)Īs we know, all files saved on a hard disk ( here we refer to mechanical hard disk rather than SSD) are accessed via the magnetic head. There are lots of benefits to make defragment hard drive, and in this post, we just list major 3.ġ. How Does Disk Defragmentation Improve Computer Performance (Benefits)? If not, hard disk performance would be affected largely.

Once fragments reach to a certain degree, users need to defrag the disk or defrag computer. At this time, if there is no free space available after File 1, file system needs to allocate 10MB unused space from other places for the added content, which means File 1 will spread across the drive and data fragments are generated, too. That is to say, extra 10MB space is required. For example, the original size of File 1 is 20MB, but then we added some content to this file, making it 30MB now. Under this situation, we say data fragments are generated.Īctually, apart from deleting and writing operation, editing or modifying an old file may cause fragments. The new file is made up of 2 parts: one is after File 2, and the other is after File 5. Supposing File 3 releases 2MB space but a 3MB file will be saved to the released 2MB space, what will happen? Definitely, space released by File 3 cannot hold all content of the new file, and file system has to allocate more space for this file from other released space or unused space. However, after one of these files is deleted, for instance File 3 is deleted, space occupied by this file will be marked available for new files, and file system can save any new file to the newly released space even if there is unused space left at the end of the drive ( file system just allocates space at random). Generally, when we are saving files to a new partition or volume, all files will be saved continuously, for example:

But at this time some users may ask why a file could be saved to several different locations on a drive rather than stored in one place. Now users would know how disk defragmentation works. Defragment hard drive is the process of putting these 3 pieces of data together so as to make a file saved in continuous space, as the following picture shows: That is to say File 1 consists of 3 pieces, and each cluster holds one piece. Suppose: there are 10 clusters in one partition, and a file uses the first, the third, and the ninth cluster since one cluster cannot hold all content of the file, like this: Maybe it is difficult for some people to clearly know the very process just after seeing the description, so next let’s see a specific example. Therefore, we compose this post by answering these questions one after another.ĭefragmentation is much related to file systems on electromechanical disk drives, and it is the process of picking up all pieces of data which spread across a partition ( it is also called volume) and then putting these pieces together. Maybe, some of you have a great understanding of one or more questions, but most people just know little or even nothing about defragment hard drive.
