So if I want a cheap device, I should stick to RPi 2.

Okay I see, thanks for the explanation. Netgate FW-7541 is indeed very expensive. A recent ARM CPU and proper networking and a SATA port would be very nice of course.

What I need actually is a system that can run a linux debian version and has a good price/performance ratio. Saying when I compare Raspbeery Pi and A20-OLINUXINO. I see major differences in the network controller, SATA support, CPU and RAM. Raspbeery PI has only one controller for both USB and ethernet, where OLINUXINO has a native ethernet interface (not an USB to ethernet converter like RPi). RPi has a quad core 900Mhz where OLINUXINO has 1Ghz dual? and OLINUXINO has a gigabit ethernet .
