USB performance improvements
Increased speed when using USB storage media with NTFS data systems
If you're using USB sticks or flash drives on your FRITZ!Box that are formatted with the data system NTFS, you can benefit from increased speed during transmission.
You don't have to do anything – just continue to use the existing USB storage media as before.
To check what data system is used, go to Home Network -> USB Storage Media in the FRITZ!Box user interface.
