I've seen plenty of threads asking how big of an SSD is needed for Win10. It is always the same answer - "you want at least 120 gb to have room for other programs etc - 250 gb is the ideal minimum". Thing is - I got a 250 gb SSD already, but I have a spare 50 gb SSD that is not being used. And if I decide to put that in it will be solely for Win10. Should that be fine? I see that Windows should only take around 20 gb.
