Microsoft has also developed their file system for Windows, NTFS. This proprietary file system was introduced in 1993, and it supports metadata and advanced data structures to improve performance, additional extensions for improved security, and file system journaling. Unfortunately, these two file systems are not suitable for flash drives because of their limited support. The best file system for modern flash drives is FAT32.

That’s because most of the computers in the world run Windows, and Windows uses a different file system, usually one known as Fat32. Drives formatted as Fat32 can be read from and written to by macOS, but it’s not optimal and you’re more likely to run into problems than if you use macOS’ native format.

If your Mac is running macOS High Sierra or later, you have two options for file formats: APFS and Mac OS Extended. Which should you choose?

APFS is optimized for SSD (solid state drive) such as flash drives, so if you reformat a flash drive on a Mac, you should definitely choose APFS (unless you plan to use it with a pre-High Sierra Mac, of course). Even on hard drives, however, APFS is faster and more reliable than Mac OS Extended. Finally, if you plan to use the USB drive as a destination for Time Machine backups, choose Mac OS Extended. Time Machine can’t currently back up to an APFS disk and if you select one for use with Time Machine, it will offer to reformat it as Mac OS Extended. You can, however, backup an APFS formatted disk to a Mac OS Extended Time Machine drive.
