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.

      Just for reference

      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
