Since you have to uninstall it for major updates on Windows 10 it is not that big of a deal. If your drive is at less that 25 % of capacity it is also not that big of a deal. You can TRIM manually when RBRx is uninstalled once every couple of months or do like Umbra says above. I never had problems with it. It was one of my most reliable softs. Others had problems with it because they piled bunches of other softs on top of it - especially other backup\recovery solutions. When it comes to Windows, less is more. You really are better off using Chrome OS if you are paranoid about stuff.
