iotop equivalent?

[Forza]

Is there a iotop equivalent that lets me watch the total MiB/s read/written by process?

I have the same question. I'm running Truenas Scale and there's only ionice and iostat. With the iostat I see that some process writes every 2-3s to the drives in zpool, what drives me crazy, because the drives should go to sleep after 30min of idleing. iotop would help to identify the process doing writes(or reads).
