Reply to Question Regarding Laptop Storage

(I apologize if this thread is in the wrong section) Hey, I'm extremely new to music production/performing and I'd just like to ask a question that I couldn't seem to find an answer to.

Until I can afford a full-fledged desktop for music production, I'll be using a T420 (maybe T430s) ThinkPad. I'd like to swap out the hard drive with an SSD and I'm wondering: Is a 128-256GB SSD good enough for light, minimalistic hip-hop beat production PLUS performing? Or should I opt for a 500GB SSD?

Keep in mind that I will not be loading this computer with a lot of programs.

Any help is appreciated!
