The Mac OS Extended (journaled) format is best for the organization of data as it uses Journaled HFS Plus. The Encrypted option increases the security with password and encryption, while case-sensitive differentials folders with upper/lowercase letters (“September” and “September” stay separated, etc.) You can choose the best option for your case but we recommend that you go with the fourth format as it comes with three different options.
