exFAT is an improved version of FAT32. It isnât as efficient as NTFS (Windows) but is cross compatible between Windows OS and Mac OS (since 10.6.5), unlike NTFS and HFS+. I recommend using it when compatibility between Mac and Windows is important, at the (small) cost of efficiency (such as file size bloating, transfer speeds, general performance). exFAT is the preferred format for flash memory, used for media such as SD cards and SSD.

In a Windows-based environment, USB flash disks may be formatted using three different file systems: FAT32, exFAT and NTFS. The FAT32 file system is a mature file system, which is an improved version of the original FAT file system used in the MS DOS operating system. Later, Microsoft introduced the NTFS file system, which improved the performance and reliability of file operations. Finally, in 2006 Microsoft added the exFAT file system, which is especially optimized for flash devices and resource constrained hardware configurations. 1  FAT32 - a mature file system normally used on USB disks. 2  exFAT-a newer file system optimized for flash devices. 3  NTFS-an advanced, journaling file system.
