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.

Is it worth switching to BTRFS for the average user? (aussie.zone)

I'm having trouble understanding all the benefits of BTRFS and how they'll apply to me.

Copy on Write and auto-compression seem like they will free up a bit of space.

What other practical benefits will I see from using BTRFS? Are there any noticeable performance benefits?

I use my computer to dual-boot. I don't need snapshots because I have a custom script for a fresh install. I use my PC for gaming and work. I've got an NVMe, two SSD's and one HDD.

Thanks in advance!

I thought compression would not help much with disk space as well. I believe it depends on the use case. After switching to btrfs and enabling zstd compression, my Arch install reduced from 100GB to 60 GB in terms of used disk space. Most of the savings are from documentations of development packages.

So it's 29G(43%) from / + /home, 5.3G(45%) from flatpak packages, 46G(16%) from Steam, 1.5G(47%) from Bottles, ~82G total out of 380G(22%) which is nice
