Sure thing, sorry
I am seeing constant writes to the array also;
598 be/4 root 0.00 B/s 88.35 K/s ?unavailable? dockerd -p /var/run/dockerd.pid --log-opt max-size=50m --~g-opt max-file=1 --log-level=fatal --storage-driver=btrfs

They very in size from just a few K/s, up around 20m/s is the max I have seen.
I have yet to have the system crash because of this, or had any disks fail, but this has only really been happening in the last couple of days. I initially thought that this was maybe due to transcoding video from 264 to 265, as iotop would reference the tdarr containers a lot, however even with these shut down, it doesn't make much a difference.
I never see much reference to anything else really mentioned, at least not in a constant manner.
