USB2 should be capable of transferring data at speeds up to 30MB/s. However, the fact that you are seeing slow transfers doesn't prove that there is a problem in your Synology box.
You could have a bad data port on your data switch, or a bad cable. You could have a speed/duplex mis-match causing collisions which will choke the speed down substantially.
A friend of mine bought a DS1511+ about two weeks ago and called me up swearing about what a piece of crap it was. Some investigation proved out that he had a duplicate IP address on his network (he had statically assigned an IP to the Synology that was already being used by something else on the network, duh).
So, there would be a lot more testing for you to do before you know what the cause of the slow transfer is.
But, first off I would try transferring from a few other machines on the network. Even a slow laptop hard drive should be capable of doing transfers to the Synology box over SMB at speeds of 30+ MB/s.
