File Allocation Table 32 (FAT32) is an older file system comparing to Extended File Allocation Table (exFAT). It has higher compatibility among different operating systems and old devices, such as Linux, PS3, PS4, and XBOX and so on. FAT32 uses space more efficiently through small cluster size. It is a robust and flexible file system as well.

It is not a bad choice to format to FAT32 with. ExFAT is a relative new file system that was first introduced to us in 2006. The most outstanding feature of this file system is that it makes up for the limit of FAT32, maximum file 4GB in size. In addition, exFAT works well with large-sized partition up to 8 TB in size.
