“Cluster” is very strange for most common computer users. So what is “Cluster”? What effect will it cause when we set different cluster size? According to these frequently asked questions, let’s make a brief discussion, hoping you can know better about “Cluster”.
At first, “Cluster” is the minimum unit of file storage and management in Windows operating systems. But some users may think the minimum unit of storage is sector. That is a misunderstanding. Sector is the minimum unit of accessing disk. Generally, several sectors form one cluster, and every file in the disk occupies a lot of sectors. If system manages and saves file with sector, it will waste much time and affect the operating efficiency. Therefore, using cluster as the minimum unit, management and storage in computer will be much easier and more convenient, and the efficiency of operating system is promoted. In brief, cluster size is the sector number in one cluster. We can see that setting cluster size directly affects the efficiency of system.
After knowing about the cluster and its effect on operating system, we may try to set cluster size for disk or partition so that we can improve system efficiency. However, if we try to use built-in disk management tool to set cluster size, we will find it has no such a function. Some experienced Windows users know that we can only set cluster size with built-in disk management tool when creating or formatting partition. We can’t set the cluster size of the being-used partition. At this time, what we need is a third-party partition magic. Professional third-party partition management software can set cluster size anytime without causing effect on data.
Through the above introduction, I believe you have already got familiar with the concept of “Cluster” and the effect of cluster size on computer. There might also be many questions, for example, how to set reasonable cluster size? Let me express my opinion to you.
Firstly, we should know that cluster is the minimum unit of saving file in computer, and every single cluster can only save one file at the most. Therefore, when the file is rather small, it cannot fill one cluster, and then the extra space is wasted. Thus disk usage rate will be lower. However, if the file is large but cluster is small, one file will occupy several clusters. Thus, it is quite difficult for operating system to save and manage file. So we should set the cluster size smaller when saving small files, and larger when saving large files so that we can promote system operating speed and disk usage rate.
This is only my own opinion about setting cluster size. It is practical for me so I hope it can help you, too. Please leave a message if you have any other suggestions. We can improve together then.
