The big question: what's the actual throughput? 2x1 GBit/s should be 250MB/s (or, after SMB overhead, 200 MB/s) - but even on a beefy QNAP TS-1635 I could get out only 80MB/s despite having a RAID5 of 10x WD RED disks.

This tiny thing will not go very far in terms of bandwidth. If you want bandwidth you will need a HW RAID controller.

You realize that (due to load-balancing algorithms) you probably won't see that (theoretical max) 250 MBps to a single device, yes? From one device to the QNAP you'll still see at most 1 Gbps (usually -- there are some exceptions).

Of course I do, in my case the QNAP is connected to the switch using port bonding. Each port gets ~40 MB/s, with multiple clients or with a single client.
