We tested the peak power consumption of a NAS at the wall during a run of CrystalDiskMark 5.0.2 as this version of the benchmark runs the read and write benchmark suites separately so it's easier to monitor what power the device is using during each function.

The official power ratings for the TS-451D2 are 31.5W (typical) in operation and 21.3W in HDD sleep mode.  The CPU that the NAS uses, an Intel Celeron J4025 has a TDP of just 10W which helps keep the numbers low. We could confirm these figures with our test results using four WD Red 6TB (WD60EFRX) drives which are rated at 5.3W (active read/write), 3.4W (idle) and 0.4W sleep.
