If it works exFat is preferred for large drives and copying files is much faster than the universal FAT32. Size rarely matters. (Not what she said.)
exFat works in my A&K, NOT in my Cowons.
SD card formatting
I have a 128gb SD card (SanDisk Ultra) which I formatted for a Hiby R3 Pro Saber (DAP). I chose exFat with a 128K Allocation Unit Size. My music files are Mp3 and FLAC. Is 128K (and exFat) the preferred configuration, or should I re-format to another? What would offer the best (musical?) performance? I just joined this website, so my apologies if I chose the incorrect discussion-group. Thank you for your time.
