Author may have gotten lucky in their Western Digital Blue SN550 selection. It's a fairly low power drive. WD has been making their own controllers, & they have a history of being fairly power friendly. This is a very new drive too. This review[1] shows it using 2.62 watts during a large file copy and on-idling at 0.96 watts.
The best drive shown is a Crucial MX500, using 2.32 watts during cpy and 0.52 watts at on-idle.
There will be some additional power consumption from the usb adapter too but i'd expect no more than 0.2 watts.
