I can't really tell from the information you posted so far. Could you post the repr of da_fam_bulk (print(da_fam_bulk) or display(da_fam_bulk) using ipython / jupyter, plus maybe a screenshot of the HTML repr if you're in a notebook)?

I do suspect, however, that da_fam_bulk has a dtype that is not float64, but where will use float64(nan) as a fill value, casting the entire array to a dtype that has a much higher memory usage.
