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 its easier to monitor what power the device is using during each function.
The Marvell Armada 388 processor in the N4350 has a TDP of just 5W. With a careful choice of hard drives, the power demands of the NAS can be kept to a minimum. We tested the review unit with four 6TB WD Reds, which have an average read/write power demand of just 5.3W.
