I don’t know why when i copy files to my cloud home from my pc，also sync files，then my computer will run most slowly every time.I have to reboot my pc again and againd.

It could happen because of your network topology, because transfer speed of data from drive to PC or vice-versa depends upon the network speed.

You should contact WD technical support to clear get more information on such matter.
