A:Answer Here's the thing. I have three partitions on mine.
150gb for windows, programs and apps.
300gb for compiling and building software.
And a 500 gb partition for storage.
Now when I use storage, I use it for cloud data, such as OneDrive, and Dropbox, and all of my music and documents. I also try and build sorce code for different programs and projects. That is my second partition. And everything that the system needs like windows, subsystems for Linux, unity 3-d and visual studio all fit on my c:\
Now all of my cloud storage drives consumes about 25 gb. That includes my music archives and photo archives.
So in windows 950gb is a lot of room. Hope this helps.
