Which Mac File System Is the Best for an External Drive?

Before choosing the best format for Mac external drive, you should know which file system formats are available in Disk Utility on Mac.

Disk Utility supports the following file system formats:

• Apple File System (APFS): the file system is used by macOS 10.13 (High Sierra) or later.
• Mac OS Extended (HFS+): the file system is used by macOS 10.12 (Sierra) or earlier.
• MS-DOS (FAT): the file system is compatible with both Mac and Windows.
• exFAT: the file system is compatible with both Mac and Windows.

Now, we will introduce these four Mac file systems and this information can help you find the best file system format for external hard drive on Mac.

Apple File System (APFS)

APFS is the default file system for Mac computers that are running macOS 10.13 (High Sierra) or later. It was announced at Apple’s Developers Conference (WWDC) in June 2016, meaning to replace HFS+ that was released in 1998. APFS has many attractive features like snapshots, strong encryption, space sharing, fast directory sizing, and improved file system fundamentals.

APFS is optimized for Flash/SSD storage used in recent macOS. Due to this, it can also be used with the older systems with traditional hard disk drives (HDD) and external, direct-attached storage drives. Besides, you can use the APFS file system for both bootable and data volumes on macOS 10.13 or later systems.

APFS is intelligent. It can allocate the disk space within a container/partition on demand. For example, if your APFS container has multiple volumes, the free space in the container is shared. The free space can be automatically allocated to any volume that needs more storage to save data.

When necessary, you can arrange reserve and quota sizes for each volume. The volume only uses part of the overall container. As a result, the available space is the total size of the container minus the size of all the volumes in the container.

APFS has the following four formats:

• APFS: it uses the APFS format. If you don’t need to use an encrypted or case-sensitive format, you can choose this format.
• APFS (Encrypted): it uses the APFS format. You can encrypt the volume if you format the Mac volume with this file system on your Mac.
• APFS (Case-sensitive): it uses the APFS format. This file system can distinguish the case of the file and folder names. For instance, folders that are named Work and WORK are two different folders.
• APFS (Case-sensitive, Encrypted): it uses the APFS format. This file system integrates the features of the above two formats. That is, it is case-sensitive to the names of the file and folder, and you can encrypt the volume.

You can choose the best format for external hard drive on Mac based on your requirements.

Mac OS Extended (HFS+)

Mac OS Extended, which is also known as HFS+/HFS Plus or HFS Extended, is a journaling file system developed by Apple Inc. It is using on macOS 10.12 (Sierra) or earlier. It was the primary Mac OS X file system until it was replaced with APFS.

It has the following four formats:

• Mac OS Extended (Journaled): it uses the Mac format of Journaled HFS Plus. It can protect the integrity of the hierarchical file system. If you don’t need to encrypt the volume or distinguish the case of the file and folder names, you can choose to use this format.
• Mac OS Extended (Journaled, Encrypted): it uses the Mac format. This file system needs you to set a password to encrypt the partition.
• Mac OS Extended (Case-sensitive, Journaled): it uses the Mac format. It is case-sensitive to the names of folders.
• Mac OS Extended (Case-sensitive, Journaled, Encrypted): it uses the Mac format. It integrates the features of the above two formats: you need to set a password for the partition to encrypt it and it is case-sensitive to the names of folders.

MS-DOS (FAT) & exFAT

Both FAT and exFAT are compatible with both Mac and Windows. The differences are that FAT is used for a volume that is 32GB or less, while exFAT is used for a volume that exceeds 32GB.

If you want to use the external hard drive on both Windows and Mac, you can choose to use one of these two file systems. In comparison, exFAT is more compatible.
