   No, that is true, and my Pi 4 can just handle two USB SSD drives. JUST.   
   Not three though.   
      
   BUT even doing sod all it still draws enough to get its temperature up   
   into the 50's°C. As do the drives  into the 40s°C   
      
   Which the Pi zero also does   
      
   I think that as a desktop machine Pi 4s and 5s power consumption is   
   approaching that of a good intel chipset *for equivalent performance*.
