exFAT has been chosen by the SD Card Association as the standard file system for SDXC cards with 32 GiB or more of storage. Sadly the Fedora Project has chosen not to bundle support for exFAT due to patent issues. A free implementation of exFAT has been made and is available via RPMFusion Free for RPM based systems.
$ sudo dnf -y install https://download.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
$ sudo dnf -y install fuse-exfatIf you now try to mount your SD-card in Nautilus for example it should mount your drive. The performance should also be better than with NTFS as there is less overhead.
