SD Card Format


I'm using a SanDisk 64G SDXC card. SDXC cards are formatted exFAT by the manufacturer. I'm using mine as is and it seems to work well after attaching it to the file system. I wonder, though if it wouldn't work better formatted to NTFS.

Has anyone done any performance testing with exFAT vs NTFS?


I am told by others on the forum that exFAT works fine. I formatted mine to NTFS when I put in the slot just so the file systems are the same. Only reason I did that.

Just yesterday I was playing with my card, which was exFAT. Moving Pictures, Music and Videos folder, I get somewhere in the 10MB transfer range. With NTFS, it went down to 6MB.

I'm back to exFAT.
