The free fall sensor relates to a conventional drive so no, its not relevant.
As to the rapid storage... well I would let Windows (am I really saying this lol) do its thing before you consider adding what could be out of date drivers from Dell. I recently did a clean W10 install onto a new SSD on a Dell Vostro and the only missing driver was for the card reader. See what Windows does first. If something isn't working only then try the driver.
For interest I would suggest run the Windows assessment tool as well. From an elevated command prompt enter,
C:\Windows\system32>Winsat formal -restart clean
My results were spectacular for a laptop,
