Cluster size refers to the amount of space allocated to each unit of data on a storage device. A larger cluster size can improve performance for large file transfers, while a smaller cluster size can reduce wasted space for small files. Checking the cluster size of a storage device can help you determine the optimal settings for your specific needs.
There are a few different ways to check the cluster size of a storage device. One common method is to use the “fsutil fsinfo ntfsinfo” command in a Command Prompt window. This command will display the cluster size, along with other information about the file system.
