@shanls96 - I think it really comes down to personal preference. I have a 256GB SSD gaming laptop. I have all the packs. My game loads pretty fast, and I dont' really have issues with load times when traveling. But I only use the computer for gaming. My previous computer was a HDD, it was slow in my opinion for running TS4. & I had so much space when I got rid of that computer as I really didn't use or need all that space, so that's why I opted for the 256GB SSD this time around.
So if you're planning on using the computer as your main OS plus gaming & you plan on doing a lot of gaming, you may want to get more space, as previous people mentioned. I'd recommend just doing some research to see what is the best fit for you.
