Ugreen NAS Power Consumption …
For devices that are typically left on and active at all times, it’s important to know how much power they consume. That’s why we monitored the NAS’s power consumption in various operating states. Power consumption was measured using a Shelly Plug S, which, while not super accurate, provides a pretty good indication of consumption.
In standby mode with the NAS powered off, the device consumes approximately 1W. This is likely due primarily to the power supply being in standby mode, as well as parts of the system that are already active when the device is powered on. During startup, power consumption ranges between 12W and 15W for one to two minutes; after that, consumption stabilizes at 9W to 11W in idle mode.
When copying several gigabytes of data over the network to the NAS, we measure a power consumption of 12W to 13W. However, this also depends on how the hard drives are configured. In a RAID-1 setup, data is written to both hard drives simultaneously, so both drives are active (as in our case).
During a stress test with 100% CPU load across all 8 cores and maximum throughput when writing data to the hard drives, power consumption briefly rose to 15W to 17W. These are quite good figures, resulting in an annual energy consumption of approximately 110 kWh—equivalent to about 30 Euro in annual energy costs for continuous operation.

Ugreen NAS Performance …
To test the transfer speed to and from the NAS, a Mac Studio M2 Max with a 10Gbps network port was used, connected to the NAS via a 10Gbps switch. The DH2300’s 1Gbps interface is the limiting factor in the network here, and the measured throughput of approximately 112MB/s (944Mbits/s) is quite close to the theoretical maximum.
Since the iperf3 tool measures only raw network speed, we also used the “Blackmagic Disk Speed Test” tool to measure the speed of data transfers over the network to the hard drives. Here, too, we achieved speeds of over 100 MB/s during sequential data writes.
