What should I put in a 120gb SSD or a 250gb SSD?

[IAEInferno]

So I was wondering if it is okay to put my OS on a 120gb ssd and a few apps like Adobe premiere pro, Photoshop, After Effects?

 

With a 250GB SSD can I also make it a scratch disk along with the Operating system Adobe Premiere pro, Photoshop and After Effects?

put your os and mostly used apps

Doesn't seem like it is recommended as per this Adobe forum thread:

 

"It is recommended to keep Scratch disks  on a different drive than the one your operating system uses.

You can partition the new drive and if required assign the second partition to Photoshop in future as well."
