Power

We were quite surprised by the power usage of the Lockerstor 2 Gen2+ AS6702T v2, as we saw the same Intel Celeron Processor N5105 in the Nimbustor 4 Gen2 AS5404T, yet we're seeing a much lower power usage here that can't simply be explained by the AS6702T v2 having a pair of drive bays less. It obviously doesn't get close to the Drivestor 2 Gen2 AS1202T in power frugality, but it seems to be a good option for anyone looking at getting a power efficient NAS that still has enough CPU power to handle things like a bigger photo or video library. Even peak power usage didn't reach the power usage of the AS5404T with the disks sleeping, but we can also see that more modern hardware like the Intel Processor N150 in the TerraMaster F4-425 Plus is a smidgen more power efficient with the drives sleeping. The only thing that is not very good is the standby power at 1.8 W, although this just meets EU regulation for standby power, it's worse than we've seen from Asustor. We're not quite sure why this is the case, as the power adapter appears to be the same as the one that shipped with the AS1202T, and it had a standby power of a mere 0.5 W and the AS5404T was similarly at 0.7 W, despite coming with a 90 W rated power adapter.

Noise

The Lockerstor 2 Gen2+ AS6702T v2 was quiet in use, most of the time it was the hard drives that were causing most of the noise. Part of the reason for this was that the auto fan speed at around 840 to 850 rpm didn't cause much noise, despite the use of a 70 mm fan. Even at full tilt at around 2230 rpm, the fan didn't produce all that much noise, at least not compared to most NAS units we've tested so far. Keep in mind that we measure the noise at the rear of the NAS, so this would be like having it on your desk right next to you, with the fan facing you. In use, we could only hear the drives when under heavy load, much as you would with any other NAS that has mechanical drives in it. The AS6702T v2 is overall a pretty quiet NAS and should not cause any unpleasant noise, even when heavily used on a hot day.

Temperature

The CPU idled somewhere around 50 degrees celcius, but we saw temperatures at around 63 degrees when the system was under somewhat heavy load. The system temperature seemed to sit at around 32 to 36 degrees celcius, with the hard drives at around 33 to 36 degrees. Even in this rather cramped space, the SSDs never exceeded 60 degrees, although in this case they were both equipped with heatsinks, and we'd expect the temperatures to be higher without heatsinks. Overall pretty standard temperatures and nothing really to note.
