About file system formats

NTFS: since it is the native file system for Windows, volumes created in NTFS are read and write with computers running Windows. Mac OS can read NTFS volumes but cannot natively write to them.
Mac OS Extended (HFS+): the native hard drive file system for Mac. Windows cannot natively read or write to HFS+ (journaled) hard drives.
exFAT: generally compatible with Mac and Windows. exFAT is not a journaled file system which means it can be more susceptible to data corruption when errors occur or the drive is not disconnected properly from the computer.
FAT32: compatible with Mac and Windows. However, FAT32 is a legacy file system designed for low capacity hard drives and it is not recommended for modern hard drives or operating systems. A FAT32 partition can reach up to 32GB when formatted on a Windows PC.

How to choose the file system format

Use NTFS if:

…the storage device is connected to Windows PCs.

Use HFS+ if:

…the storage device is connected to Macs.

You can use exFAT if:

…the storage device is shared between Mac and Windows computers.

Use FAT32 if:

…the storage device is connected to older Windows and Mac computers. FAT32 is not recommended for modern operating systems and computers.
