From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

XFS doesn't support snapshots, but it does support reflinking like BTRFS. Reflinks allow data to be shared fully or partially between two files, which means that technically with a lot of elbow grease you could probably write a snapshotting system for XFS built on reflinks. There's actually a "filesystem" named Stratis that takes vanilla XFS and layers a ton of modern features from e.g. BTRFS/ZFS onto it. Unfortunately it's not as fast as XFS because of these features so it's not a silver bullet yet.
tl;dr, BTRFS's features are useful for most users, and I wouldn't worry about filesystem speed unless you've got a very specific usecase like a database.
Nice. Thank you. I've learned a ton from just a couple of comments. Much appreciated
