While NAS devices are typically much more efficient than a desktop computer, the specifications of our test system are actually very similar to that of the QNAP TS-809 Pro Turbo. Both were running an Intel Core 2 Duo E7400 processor, though our desktop was configured with just 2 HDDs and used 19% less power under load.

The TS-809 Pro Turbo used 35% more power than the Synology DS409+ and double the amount consumed by the Promise SmartStor NS4600. These results are not as surprising when you consider the powerful hardware inside QNAP's device. It will be interesting to see if similar margins ensue when it comes to performance.
