your laptop is new.
Windows is probably fetching updates. This is one of the differences between win 10 and 7.
Just to test, You can go to Services, and disable Windows Update service.
Don't disable superfetch.
Also, each drive partition has an indexer you can turn off.
I bet if you boot up in safe mode, you won't have the disk thrashing.
So the problem is background services, not the laptop itself.
In Task Manager, you can see which app is hogging the disk usage.
