Because saving all your data on the Cloud is nice and all, but physical storage is still popular. Especially if you don't have a stable internet connection or if most of your files are large.
Luckily, you don't have to learn rocket science to be able to format an external hard drive for Mac or PC. The operation is pretty straightforward. When it comes to your iOS device, we have listed two methods for you, read below and explore more.
Part 1: What Is the Best Format for External Hard Drive Mac?
The first step to formatting your external drive for a Mac computer is choosing the right format. There are four possible choices:
- APFS (Apple File System)
- HFS+ (Mac OS Extended)
- exFAT (Extended File Allocation Table)
- FAT (MS-DOS)
To understand which is the best for you, let's have a comprehensive overview of each of them.
1. Apple File System
The APFS was first introduced in 2017 as a replacement for the HFS+. Nowadays, all new Macs come with the operating system preinstalled on APFS, as this system is optimized for use with SSD and flash storage drives. However, it still works with traditional HDD drives too.
This is the best format to pick if you have an external SSD or USB flash drive that you don't intend to use with a Windows device.
The biggest strength of this system is the speed, as well as the encryption and metadata handling. However, you won't be able to use this system with Time Machine.
2. Mac OS Extended
The HFS+, or Hierarchical File System plus on its real name, was the main file system used for Mac until 2017.
This type of file system is suitable to use with both HDD and SDD drives, but the latter will perform slightly better with the APFS mentioned above. If you have an older Mac, though, choosing the HFS+ is your best bet.
In general, all external drives formatted to HFS+ work nicely with older Mac versions but are incompatible with Windows.
3. Extended File Allocation Table
Designed by Microsoft, the exFAT is a good choice if you plan to use the external hard drive with both macOS and Windows systems. Yet, you won't get top performance on either. This choice is more appropriate for USB flash drives, although you can still use it for SDD and HDD units too.
The main issue with exFAT is that your drive will be more prone to fragmentation when used with Apple devices and is less stable than NTFS on Windows. If you really have to share the drive between Mac and Windows machines, that's your best option though.
4. MS-DOS
Macs also support FAT32 drives, marked as FAT in Disk Utility. This format should be avoided at all costs unless you're dealing with a really old Windows computer, which you really have to use in parallel with your Mac system.
Typically, there is no reason to choose this option unless you're planning to use the external hard drive on a Windows XP or earlier machine.
