    Looking at setting up a Mybook Duo in RAID 1 (10TB | 2x10TB) to use as my backup. Needs to be able to read/write with both Mac and Windows, I was thinking exFAT. Has anyone had experience with this?

    I'm always a bit apprehensive about using any FAT file format. FAT by its nature is a non journaling file format and is more suseptible to errors than a journaling file format. You could format the MyBook as NTFS and install something like Paragon NTFS for Mac. Just a suggestion.

    Thanks, I am a bit apprehensive to use FAT as well. It’s fine for SD cards and USB sticks but I don’t know if I trust it to hold huge amounts of important data.

    Why couldn’t Apple and Microsoft just agree on one standard?

    Why would they? Linux also has a different File System. Microsoft wouldn't change their File System to suit Apple and vice versa. None of them are interested in paying royalties.

    Just use Paragon NTFS for Mac, it's brilliant.

    Not a raid setup but I have bunch of external hard drives, usb powered and additional powered. All in exFAT. Been using for some time now to do stuff in my mac and friends' PCs. All fine.

    All my external drives have been formatted as exFAT for years, never had a problem.
