It looks like Runeaudio is Arch-based. Archlinux on the PI is pretty easy to run on the f2fs filesystem instead of ext4.
F2FS is a fairly new filesystem, gaining traction especially on Android devices but also on other flash-based computers.
It is designed to be used on cheap flash-units like USB sticks or SD cards, which do not have expensive controllers like full blown SSD drives.
F2FS gives a much higher performance on those devices, but more importantly, it lenghtens their livespans by not always writing the same location of the drive. Ext4 is not 'flash aware' and will therefore wear out an SD card faster than f2fs.
F2FS is already included in the kernel; You only need 'f2fs-utils' to create a filesystem, and an option in the bootfile saying 'rootfs=f2fs'. More performance and greater durability, at the cost of a one-time action.
