sorry to tell you guys. I just reverted to Windows 10 as I am quite sure N3700 is not full compatible as follows:
1. the disk is not idle although it logs "internal hard disk wake up from hibernation".
Proof: the temp is higher than that of windows.
2. CPU is running at normal speed always. Not speedstep or slow down.
Proof: Win10 power consumption (idle with sleep and hibernation disabled) is 15w whereas DSM 5.2-5644 update 5 is 35w. Both are running on 1xSSD+1x4T HD+1x2T HD. The most interesting thing was when both were working on lan backup, they consumed the almost the same power：35~40w.
