I know it's larger than the one I just gave away which was 0.7 cu. ft. But it sure is louder. So far I'm noticing that there isn't any water pooling under the turn table dish which is good as that was happening so much with the old one. I had one by Gold Star I think 1 cu. ft.  for 27 years with no problems at all and hope this one will be just as good and serve me well.
