Our experience with the Akitio MyCloud Duo was miserable and that comes just from the performance and user interface. Once you add in the dropping off the network, never being able to hit the NAS hard with file transfers or the intermittent "it just isn't there" problems, you can understand why we would recommend you stay far away.
Even if all of these low level issues were fixed that still leaves the file transfer performance. If Akitio didn't claim gigabit performance, we wouldn't really care so much, but 1000mb/s is available on nearly every NAS on the market and the Akitio can't get anywhere near those speeds.
On a positive note the price is only around $150. Then again you might feel like you wasted $150 if you get a product that performs and behaves like the review sample we received.
