Does a laptop with a 256GB SSD have better performance than a 128GB SSD (where both have 25% of the drive empty)?

This article claims that the bigger drive has better performance just by virtue of it being bigger, is that true?

Relevant section:

Performance scales up with higher storage capacity with the same model:
A 500GB Samsung 850 EVO offers higher performance than its 250GB variant. The difference in performance between the 120GB and 250GB models is larger than the difference in performance between the 250GB and 500GB models, even more so than the difference in performance between the 500GB and 1TB models.
So if you want even higher performance, youll be better served by an higher capacity SSD.

Depends on SSD but generally 12x GB SSD's are indeed slower than 2xx GB SSD's as bigger SSD's can do more internal things parallel.

I don't recommend getting any Samsung Evo drive though.

I'm referring to internal SSDs that come with the laptop.

Then we have to know exact models, because that speed difference is only applicable between same model but different size SSD's.

SSD model is not specified so I would apply general rule: bigger=faster.

Are there any internal SSD models that the storage capacity doesn't affect the performance, and where it makes no difference how many GB it has?

I don't think there are any models where capacity does not matter performance wise. It's still possible though. Capacity generally matter least on read speeds and seek times, but generally everything is faster. Usually goign from 12X GB to 2xx GB makes more difference than going from 2xx GB to 4xx GB.

You probably can switch retail SSD drive on laptop if you want. Depends on laptop how hard that is.
