What is better? A laptop with?
Depends on what you have in front of the laptop. If you just go with it, the 512 GB HDD is better. If you want to do more, prefer the other station wagon.
I would like to study computer science soon. That's why I think I'll have to store a lot of files on it. And of course I also broke it for programming. But I'm not sure if the 128 GB ssd will be enough for the programs. I really do not want to save it to the "less secure" hdd
Speed or storage space. That's the decision. We can't take it from you.
So 128 Gb are a bit tight, you'll have to dodge the HHD. I have a 250 GB SSD, with Win 10, which is half full, although I have only a few simple programs with it.
Longer battery life. Quieter. Less heat.
If necessary, an external HDD
So I have a 128 GB M.2 SSD and that is with ALL programs that I use just 60 to 70 percent full. And that includes Python, IDE, Android Studio and all other programs.
It may be, as I had reinstalled Windows (with programs), I was even under it, but Windows mulls over time, one is then constantly forced to clean up.
I just checked. On my notebook, which is really only the bare essentials and that I almost do not use, it is also 80 GB
Funny, had never cleaned up my SSD before
