New PC and solid disks

Hello, I bought a new PC, and I would like to install the Professional Cakewalk that I bought a few months ago, since until now I was working with the Artist. In the new PC I have installed two solid disks, one for the system and one for the samples, and a mechanical hhd disk, the question is, 1- I can install the folder Cakewalk Content, on the ssd disk that I do not have the system, or should I install it in the system? 2- The audio and midi files that I record with the sequencer, should I archive them on the second disk ssd or on a common hhd mechanical? I wait for your answer Thank you very much!!                                                   

First it somewhat depends on how big your SSD drivers are. And the speed of your  regular HD. 
If your not going to use the computer for much else you can install Sonar to the C drive and even the content will fit. I only have a 128 GB C drive on my DAW and its still is at about 50% I have  3 versions of Sonar and a bunch of other software on it as well, But I do not store any Data on the C drive. As Bitflipper said I leave Sonar to store everything there, I only park 3rd party Libraries elsewhere.  
I use a second 128 GB SSD drive for Data and my working files in Sonar. Projects load nice and fast with the SSD drives. 
Then all my back ups and some VST libraries are on a 7200 1TB 3rd drive . 
Most VST installs including Sonars will allow you to select a pathway for the content during install so it's up to you. 
If your regular HD is 7200 RPM then your good to go with sample libraries but I won't use it if it's 5200. 
 

What Bit said.  Simple and easy.

No, I'd think not. I'd like the speed. We use SDD drives all the time for critical systems. That's just IMHO.
