Is it worth switching to BTRFS for the average user?
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.
Transparent compression, snapshots, copy-on-write, deduplication, and data checksumming (and healing via read or scrub) are the main things you might notice as an end-user. BTRFS is mostly on par or slightly slower than other simpler filesystems for speed (can be faster on HDDs due to compression), so if you're using it you probably want to be taking advantage of the features it offers, not because it's going to be faster.
Healing won't work without copies (RAID) available. However, scrubbing regularly can also allow your drive to detect and correct errors before they become irreparable.
