Transferring files from MyCloud home very slow

The quoted really has little to do with the My Cloud Home (MCH). The recent firmware has improved throughput to the MCH HDD to the point which is similar to that of a typical (slow) 5400rpm HDD share on GbE (ethernet). The original USB suggestion above still stands however, since the MCH is capable of ~300 MBps write to a fast SSD USB3.
