    Allocation Unit size when formatting SD card?

    So I am reformatting a few SD cards on MS Win 10 64 in exFat, but Windows is also asking the allocation unit size, the default seems to be 128 KB, but there are 20 other options. What have you found that works best in P4p+ for video? Thx edit:Lexor 64GB 633x SD card
