Should I use btrfs or XFS?
Advantages of Btrfs over XFS The Btrfs filesystem is a modern Copy-on-Write (CoW) filesystem designed for high-capacity and high-performance storage servers. XFS is also a high-performance 64-bit journaling filesystem that is also capable of parallel I/O operations.
Is XFS a good file system?
If both your server and your storage device are large, and there is no need to shrink (reduce) the filesystem size, XFS is likely to be the best choice. Even with smaller storage arrays, XFS performs very well when the average file sizes are large (for example, hundreds of megabytes in size).
