  • Smaller clusters might significantly reduce disk space losses related to the fact that any file occupies at least one cluster/block. However, reducing FAT32 partition cluster size might increase the space occupied by the file allocation table (FAT) and slow down file access.

    NOTE: If you like to change small cluster size to large, you need keep more free space for the partition.
