I completely understand that I wont be able to get full 1000mbit performance from this device, I just think that sub 100mbit is very poor. I would have expected somewhere in the ballpark of a Dlink DNS-323 or N2100 which both have gigabit connections too.
I am running all cat6 and have a netgear prosafe GS105 5 port switch.
I am running 2 laptops and a desktop which all have gigbit, and all have similar read/write speed to the N299. I cannot use netgear NIC's. Nor should I need to as all my existing setup runs very well together.
The N4100+ also has a more powerful CPU.

They aren't lying when they say 1000 Mbit connections. The problem is that the processor will max out and not let the network interface do it's job.
You'll never get gigabit performance from these devices, or any NAS in the sub $1000 range.
The best thing you can do is use a netgear NA311 gigabit card with the latest driver.
The next thing to do is get a high quality CAT6 cables. The one that Thecus includes is not the best quality.
Then get a netgear prosafe gigbit hub. Make sure the thecus box and PC's are using the gigbit hub.
After doing this I was able to get 75 Mbps write speed from my 4100+ and 125 Mbps read speed. That turned out to be 10% better than thecus could obtain in their setup.
