PCIe M.2 SSD has constant access

Unfortunately, I have encountered a new problem when setting up the PCIe M.2 SSD.
The M.2 / PCIe adapter used:
is equipped with LEDs, which display the activities of the M.2 SSD.

I noticed that after the clean installation of Windows 10 (1709) and programs, the secondary clock accesses the SSD. Even after 2 days of running time does not stop. The LEDs are off for no more than 1 second.
Do I need to protect the SSD some business, if so, what? Or is the behavior OK?

M.2 / PCIe adapter

What is a secondary clock and how did you verify, that it accesses the SSD?
If it should really be a problem, which is caused by the M.2>PCIe adapter, you should better contact the manufacturer of the adapter.

Typical misunderstanding by Google translator.

If you want to know, which applications are permanently running in the background, you should start the task manager and hit the tab “Startup“.
Maybe you should disable some of them.
