Alright, I can verify that. I just tried with a fresh install of Cygwin and rsyncd. Copying an 8GB file via rsyncd yields about 14 MB/s. Using plain smbclient, I get "average 40119.7 kb/s" which is about the maximum write speed of the RAID. Maybe there is some tuning possible with the socket options configuration parameter. I couldn't find any recommendations though.
