    I am going to use a new 6TB drive to backup photos/videos and I want to format it as ExFat so I can access it on a Mac or PC if needed. Is there any downside to doing this VS. just formatting for Mac OS?

    I just noticed that it seems that I am limited with the number of characters that I can use to name the drive with ExFat. What other differences/issues might there be?

    If you're going to store important Mac files on the drive that you value, I suggest you format the drive for HFS+ (Mac format).

    Keep your "Mac stuff" on a Mac-formatted drive.

    Things will just work better that way.

    My opinion only.

    The big downside to ExFAT is it is not a journaled file system, so that makes it more prone to corruption.
