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.
No surprise to see that the SSD setups used the least amount of power, followed by the WD Red drives. The idle power usage of the WD Reds at just 3.4W each was in marked contrast to the mixed disk setup which averaged out at 5.8W.
