To add to Ian.
Microsoft come under fire for many things, but there aim, with windows 10, is to make it a self contained "all in" OS. With this in miond, many of the built in functions in Windows 10, take care of, or by pass third party applications. The Rapid storage to which you refer, is one such.
I would not care to denigrate Intel's efforts to improve the use of their products, but, imho, much of this has been taken care of in Windows 10.
As Ian says, you can disable it and I doubt you would discern any difference
