Is it worth it to buy a laptop with 128 gb ssd nowadays?
That depends on what you want to do with the laptop. For normal work 128 gb rich, for photo editing (and save the pictures) it would probably be too little. In case of doubt prefer more gb…
If you're just surfing the internet, that's enough. Once you have photos, games, or big software, that's a joke. So only buy 128GB if you are absolutely undemanding and do not really want to do anything on the computer.
I would buy a laptop with either a 1TB HDD, or at least 250GB, better 500GB SSD. I would rather miss the longer load times than too small a space. Loading times too long is a condition, no storage space is really a problem.
