With an external hard drive, you can efficiently transfer large files between computers running the same operating system type, such as between Macs or between Windows PCs. However, it could be a totally different story if you plan to do this between a Mac and a PC. That's because, the two platforms have their specific file systems by default: Windows uses NTFS, while Mac use HFS+ or APFS. Out of the box, Windows can't read or write to HFS+/APFS and Macs can't write to NTFS drives.
Though the default file system is really a hurdle to use one external hard drive between Windows and Mac, there're still file systems that can connect the two worlds, i.e. FAT32 and exFAT. Thus, in order to make the external hard drive seamlessly work on both Macs and PCs, we can format our drives to one of the file systems supported by both platforms.
First, what's the difference between FAT32, exFAT and NTFS?
Whether you're transfering files between Windows and Mac using external hard drives, or other portable storage devices like USB flash drives or an SD cards, you'll be told about 3 file systems: FAT32, exFAT and NTFS. You need to firstly understand the difference between each other then choose one to format to, according to your needs.
Pros: It can universally work with all versions of Mac, Windows, Linux, game devices, as well as other devices supporting a USB port.
Cons: FAT32 comes with file size limits and drive partition limits. It doesn't support files larger than 4GB, drive partition larger than 32GB on Windows, or drive partition larger than 2TB on macOS.
So FAT32 is suitable when we want to store files of relatively small sizes and the drive doesn't have a large capacity. Otherwise, FAT32 is not the best choice for us.
Pros: The largest partition and file sizes it supportted are nearly unlimited by today's standards.
Cons: exFAT file system is not compatible with older operating systems. We must have macOS 10.6.5 or newer, and PC need to be Windows Vista SP1, Windows 7 or newer.
As most users have upgraded operating system, it is actually quite easy to meet to lowest operating system requirements of exFAT. So exFAT can be a very good option to share external hard drive between macOS and Windows.
Pros: It is the default file system on Windows and has faster writing and transfering speed, better performance than FAT32 and exFAT.
Cons: By default, NTFS is read-only on macOS.
Actually, we can enable NTFS write support on macOS only with simple method. So read-only can't be a reason for us to give up using NTFS, especially when we have high requirements on transfer speed and performance of drives. Keep reading, you'll learn how to enable NTFS write support on macOS.
