Power Consumption
Let us now check on just how much power the DS1520+ needs in sleep, idle, and during heavy throughput. I use a GW Instek GPM-8212 power analyzer for all power consumption measurements.
Idle and Load
Power consumption is low. Expect higher numbers with HDDs instead of SSDs installed, of course.
Power Consumption in Standby Mode - Comparison Graphs
Vampire power, or phantom load, is the amount of energy a device consumes when 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 slightly above the 0.5 W limit with ErP disabled.
