It's been perfectly stable since years for me. Not using Raid 5/6 of course!

  Are you using snapshots? qgroups (which you have to enable to see snapshot space utilization)?. I've had bad experiences with them on btrfs.

    not OP, but using btrfs for 0.5 year with snapshots, snapper (which creates snapshots every hour) on NVMe under Arch. Haven't noticed any issues yet - qgroups are disabled, and snapper config decreased to have no more than 20 snapshots.

      Ya, I was using snapper but didn't restrict the number of snapshots so I probably had more than 20 I use zfs now and have many, many, more than 20 snapshots without issue. I wasn't using a nvme drive with btrfs, it was a sata ssd. So perhaps the higher io ops or lower latency also helps.
