Just plug the unit into your router usb port via it's usb 3.0 port/cable. You may want to fire up FreeNas to get things cooking. Use this 2nd promocode BTEJHHF38 for another 15% off. New CR-H458 total of $104. Insane price for hardware raid, 4-bay, hot-swappable, usb3.0 and eSata, all aluminum, and external.
As for that Synology, you want hardware raid (not software), a night & day difference. And also a hot-swappable backplate and 3.5" hdds...not 2.5". Stop over-thinking this. Do you realize you could get THREE CR-H458's and 48TB of RAIDed NAS storage for the cost of this gimped Synology?
That is a great option and I agree I would like hardware raid, I am worried about transfer speed of streaming HD content (1080p) over WiFi/N, what has been your experience with that kind of setup kleinkinstein?
