How to Change Allocation Unit Size for exFAT Besides, if you want to learn more information about the default cluster sizes for other file systems, you can check out this post from Microsoft: Default cluster size for NTFS, FAT, and exFAT.

So we get this conclusion: if the size of the files you want to store on the drive is large, then a large cluster size is recommended, which will increase the data read-write speed.

And that’s why you should set cluster size reasonably. If you save small files to file system with large clusters, a lot of disk space will be wasted.

Therefore, if you save large files to a drive that uses small clusters, data read-write speed will be reduced, because each file is broken into small pieces and it needs time to gather all the broken pieces and access them as one. If the file's actual size is more than a cluster, the file will take up two or more clusters. This is to say, if the file's actual size is smaller than the size of a cluster, it will still take up a cluster. One cluster can only hold one file, but one file may take up multiple clusters depending on the file size and the cluster size.
