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 how much power the device is using during each function.
At the heart of the TVS-872XT-i5-16G is an Intel Core i5 8400T processor which has a TDP of 35W. QNAP’s official power consumption figures for the NAS are; 65.03W in operation and 41.47W in HDD standby. These figures are from using eight WD10EFRX 1TB drives (average 3.3W read/write, 2.3W idle, 0.4W standby). The 6TB WD60EFRX drives we use for testing have average power ratings of 5.3W read/write, 3.4 idle, and 0.4W standby.
