Ideal storage setup

[Emmpii]

On my build, I've got the following kit available:

 

1. 1TB SanDisk Extreme Pro m.2 NVMe 3D SSD

2. 1TB Crucial MX500 SSD

3. 1TB HDD (I don't know which one but it's one I swapped out of my laptop for an SSD)

 

Now I want to know what would be the ideal setup. 

 

The main reason I've gone for a strong build is to be able to game but I'll obviously be doing work on it as well. Gaming is what it'll be used for more than any image editing etc.

 

I was thinking of using 1 for my windows installation and commonly used applications. 

 

As for drive 2 I was thinking of putting games I play often on there while using the 3rd as general storage from music, to media etc. 

 

1) Is that a suitable setup or should I consider an alternative?

 

2) I know storage prices have been dropping even for SSDs, and HDD's are dirt cheap. I was thinking of probably upgrading one of either 2 or 3. What should I primarily look at upgrading?

You've pretty much figured it out.

Fast storage: OS/Applications/Games

Slow storage: Videos/Music/Photos/Documents

 

If you want to introduce a third storage media into the mix (SATA SSD) you could use it for large files you want to access quickly.
