Filesystem qts.

I have upgraded my ReadyNAS Pioneer Pro, and in the midst of upgrading my Ultra 2. Before I complete the whole I have a question;

An external cradle for 2 HDDs is attached to my Ultra 2 via USB. The 2 disks are 2x4TB disks, and it worked fine under 4.2.27. They are both reformatted with EXT4, and I wonder if v. 6.2 uses another FS? And if it does, would there be any advantage in reformatting the two HDDs? They are both pretty full with backup data, and that's a few days of running backups...

    OS6 uses btrfs on the internal drives, but supports ext4 for USB backup.

    It is supposed to be more robust.

    But ext4 is easier to mount on other systems, so I'd stick with ext4.
