The title says it all. I use mainly wireless networking in my house, and I am wondering if the Airport Extreme is fast enough to use the DS412+ at maximum, or near maximum speeds. Does a DS413 make more sense? The NAS would be connected directly to the Airport Extreme, with gigabit cable. Can I use the Link Aggregation feature of the DS412+ with the Airport Extreme? If I don't use Link Aggregation, can I connect one network port to my Airport, and one to my PC directly? The price difference between the two models is about $150, so I wouldn't mind paying extra for the DS412+ for future-proofing or possible future wired networking or 802.11ac. Actually a lot of questions there. Thanks!
