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*.

(these temps may be of interest)

PI 4B (headless) equipped with 2 SSD
=======================
CPU temp=52.1'C
Disk 1= 40°C
Disk 2 =44°C

PI zero 1  (headless)
===========
CPU temp=43.9'C

PI zero 2 (headless)
===========
CPU temp=39.5'C
