Power Consumption And Test Setup

NAS Attack: Network Storage From Thecus And Western Digital
By , Patrick Schmid

Power Consumption

Both devices require very acceptable amounts of power. WD’s MyBook consumes only 15W when it runs idle; using the low-power WD20EADS Caviar Green drives at reduced spindle speeds certainly contributed a lot to the low power consumption numbers.

We installed two Seagate Momentus 5400.6 hard drives (ST9500325ASG) into the Thecus N0204. These provide 500GB each, they come with 8MB cache, and a 5.400 RPM spindle speed. Using this configuration, the Thecus NAS device required as little as 6W idle power, which is an amazing result, as it is less than your DSL router might require.
