Power Consumption

Let us now check on just how much power the DS920+ needs in sleep, idle, and during heavy throughput.

I use a GW Instek GPM-8212 power analyzer for all power-consumption measurements.

Sleep, Idle, and Load

Power consumption is low, so you can have this NAS operate around the clock. However, keep in mind that these power consumption measurements where taken with SSDs installed, which consume much less energy than hard disks.

Vampire power, or phantom load, is the amount of energy a device consumes when it is switched off but still plugged into the power grid. According to the ErP Lot 6 2013 directive, vampire power should be below 0.5 W.




Vampire power is a bit above the 0.5 W limit with ErP disabled.
