xfs is less prone to fragmentation than ext4,
particularly when mounted with a suitable allocsize=nnn parameter.
Not that fragmentation actually matters much.

More important, is that xfs behaves far better than ext4
with very large (many GB in size) files, particularly when
deleting them.

I've tried JFS, ext3, ext4, and xfs for my recordings partitions,
and xfs always wins, big time.
