QNAP TS-451A-4G 4-bay NAS review

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 is easier to monitor what power the device is using during each function.

With a CPU that has a TDP of just 6W, the TS-451A-4G is a pretty power efficient NAS. The 6TB WD Reds we used in testing aid the power efficiency with an average read/write power requirement of just 5.3W each, which drops to 3.4W when the drives enter their idle state.
