When you get a new external hard drive or a new SD card, you might need to first format it before use. When you format a storage device, the system will require you to choose a proper format. If you are a beginner, you might feel confused, what is the format, and which one should you choose?
Overview of File System Format
The file system is the way the system enables your storage device to store and arrange files. The main difference between all the file systems is how data is stored on the hard drive. Also, they differ from each other in file names, file permissions, and other attributes.
On a Mac computer or in macOS, there are four compatible file system formats: APFS, Mac OS Extended, MS-DOS (FAT), and exFAT. According to Apple's introduction, APFS is the "default file system for Mac computers using macOS 10.13 or later, features strong encryption, space sharing, snapshots, fast directory sizing, and improved file system fundamentals." As for MS-DOS (FAT), it has a better-known name - FAT32.
In this article, we mainly help you distinguish between the two file system formats - exFAT and Mac OS Extended. They are less common than the two earlier-mentioned ones. If you want to know their characteristics, please read on, we will introduce them in the following sections.
ExFAT is short for extended file location table, it was introduced in 2006 and was added to older versions of Windows like Windows XP and Vista. When talking about exFAT, it is necessary for you to know FAT32.
FAT32 is an old file system that is compatible with both Windows system and macOS, which is its biggest advantage. However, its biggest disadvantage is that it does not support the transfer of files larger than 4GB, so most storage devices using this format are USB flash drives.
The reason why to develop exFAT is to solve the problem that large files cannot be transferred in FAT32 format. Like NTFS, exFAT has a larger limit on file and partition sizes, so you can store and transfer files larger than 4GB.
In conclusion, exFAT is a file system that is compatible with both Windows and macOS, and it has no transfer file size limit.
Mac OS Extended
For Mac OS Extended, it has a better-known name - HFS Plus or HFS+. It is the oldest file system used on all Mac computers since 1998. On older versions of macOS, HFS+ is the default file system for all drives. Since macOS High Sierra, Apple has introduced a new file system called APFS, short for Apple File System. It is specialized in SSDs and other flash drives.
When formatting a drive to Mac OS Extended, you can see there are two choices. One is Mac OS Extended (Journaled) and the other is Mac OS Extended (Case-sensitive Journaled). In most cases, you just need to choose the standard format (Journaled) unless you need a case-sensitive system.
