I agree with this sentiment. Dual boot on a single drive (or raid0 in this case) can be done but Windows has a tendency to rewrite the boot partition which makes you unable to boot into Linux. I’m sure there are workarounds, but having them seperate is just much easier.
If you install Linux in it’s entirety to a seperate SSD, you select to boot by default into that SSD which should give you the option to boot Windows instead. The other way round is more difficult and tends to break by reasons mentioned above.
