BTRFS for Linux gaming? (lemy.lol)

I'm using EndeavourOS with ext4 file system for daily usage and a dual bootable Windows for gaming. What I want to have right now is getting rid of Windows completely.

When I tried it before, I had to try multiple tweaks for a game and find which one worked on Linux. Therefore, I want to take a snapshot with BTRFS and try it until I find the right configuration.

While I have quite a bit of experience with Linux, I've never used BTRFS. Do you think it's worth it?

I thought about keeping the games on the ext4 system, but I hate splitting the disk. I'm thinking of keeping the games in a non-snapshot volume.

UPDATE: I just re-installed EndeavourOS with BTRFS + snapper + BTRFS Assistant :)

RAID 5/6 aren't yet recommended for general use on BTRFS by the developers.

Other than that I agree it should be suitable for anything, and an improvement over ext4 in some situations.

If you don't know what RAID 5/6 is you are good.

And even then, you should probably be using RAID 10 instead. Resilvering a RAID 5 array is hard on the disks, so there's an elevated risk of the entire RAID failing. RAID 6 should eliminate this, but in a desktop system, do you really have enough space to make it worthwhile? You'd need 5+ drives to beat RAID 10 capacity, and that's a lot of space. IMO, RAID 5/6 is just not a great option in general. Don't cheap out on your RAID setup, do the industry standard, which is RAID 10.

I use BTRFS in a RAID 1 on my NAS (plan to upgrade to RAID 10 when I run out of space), and no RAID on my desktop. Everything important gets backed up to my NAS.
