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.

ext4 is better than btrfs in terms of speed right?
Yes, because it doesn't do as much to protect you from data corruption.
If you have a use case where a barely-measurable increase in speed is essential, but not so essential that you wouldn't just pay for more RAM to keep it in cache, and also it doesn't matter if you get the wrong answer because you've not noticed the disk is failing, and you can afford to lose everything in the case of a power cut, then sure, use a legacy filesystem. Otherwise, use a modern one.
But ext4 is a journaling filesystem, so a power cut shouldn't harm it.
