I have a Galaxy S5 with Android 5 and got a new 64 GB SD card. What is the best file system for the SD card? FAT32 is not an option because I want files >4GB. Which file system offers the best performance ? Thank you for your help.

The answer to your question is built into your phone's OS.
1. Put the SD card in your phone
2. Reformat the SD card with your phone(Settings --> Storage/Storage & USB)
3. The file system on the freshly formatted SD card is the type that will give you the best performance with your phone.
4. Outside the context of your phone the optimum file system is another story.

Answering the question, the filesystem used on standard Android devices is "exFAT", which is available from Windows Format application and Android's own filesytem management tools. Hope this cleared your doubt.

Ext4 should be supported because Android always supports that internally but unfortunately, the SD card is treated differently and even Android One phones do not support Ext4 for the SD card. The Nokia 7.2 Android One phone will not support Ext4 or exFAT or F2FS for the SD card filing system. FAT is the only option in 2019 !

As far as I understand you should avoid used exFAT as it is much less stable in regards to errors than FAT32, NTFS or other filesystem that can handle multiple read/write better and has multiple file tables.

As far as am aware Windows only supports fat32 if your sd card is under 8g if is over exfat or ntfs. ext4 is only for Linux distros
