Btrfs RAID5 or RAID6 having a write hole leading to potential data loss
upon hard reset has been a known issue for like a decade, and nobody has
worked on improving that [0]. RAID10 is fine though, and so is RAID1 or
RAID0. I've used it (Btrfs RAID1 with zstd compression) for years on
various Guix systems without any issue.

With my personal experience suggesting that Btrfs is a solid file
system, I respectfully disagree :-). At any rate, don't forget to
backup your precious data to somewhere safe; as RAID is no substitute
(ever had a PSU failure blowing up multiple components?).
Thanks,
