NTFS is the file system that Windows uses natively for its internal drives, and it is also commonly used for external hard drives and SSDs that will mainly stay within the Windows ecosystem. It supports very large file sizes, journaling for better reliability after a crash, and detailed file permissions.
Compatibility outside Windows is more limited than with exFAT. macOS can read NTFS drives by default but cannot write to them without additional software, and many non computer devices do not support NTFS at all. This makes exFAT the more convenient choice for drives that need to move between different types of computers.
NTFS remains a solid choice for an external drive dedicated to backing up or extending storage on a Windows computer, particularly when very large files or detailed permissions are involved. See our external SSD guide for more on choosing a file system.
