If you have synchronious writes enabled on Synology (perhaps default)
you are not able to transfer more data than the speed of the disks in
Synology. 180MB/s - 210MB/s looks like the speed of a 10k-15k SAS disk.
However, if you configure Synology for asynchronious writes the limit
for transfer is a kombination of disk speed and memory size of the
Synology with a risk of loosing data. See
