The design of the QNAP TS-470 looks exactly like that of the other QNAP NAS devices we've tested, but looks can be deceiving. Inside, a 2.6 GHz processor is churning away, and with no less than four gigabit ethernet ports this is a NAS powerhouse. 

We frequently test NAS devices and like other product segments, one innovation follows another. We try to make our tests demanding enough in order to create a clear distinction between the various products and models.
