It could be the same story as it was with Win 7 and Win 8... I think we should stay at win 10 before Microsoft will deploy some stable version of new Windows.
I'm not the expert but could give advice. Use your SSD as the main disk for the Windows and some "heavy" programs like Photoshop or game (big hello to Cyberpunk 2077), cause they would runs faster. Other things just drop into a hard disk drive.
