Each file system type has its own merits and demerits, and you can choose one based on your needs. You may use NTFS for internal hard drives and external hard drives on a Windows computer, use FAT32 or exFAT for USB drives and memory cards, or choose EXT4 for raspberry pi SD cards, etc. FAT32 is a solid file system format for removable drives, and it is used by many memory cards as well.
