Is exFAT better than NTFS?
NTFS is faster as an internal drive file system. It consistently outperforms exFAT efficiency and uses fewer system resources. However, exFAT acts faster when used as the file system for external drives as the read/write speeds are handled differently over USB connections and between operating systems.
Should I format to NTFS or exFAT?
