Does more free storage space equal to better computer performance?

If I have more available storage space, does it mean my computer performance Is better? Does that mean the lower my available storage gets, the lower my computer performance is?

Or is there a certain amount of free GB space that, if lower than that amount, will start to decrease PC performance?


For example, on one Mac, there is 40% of available storage space. On another Mac, The available storage space is only 25%. Does the mac with 40% of available storage space have better performance??


(Hard drive capacity - 121.12GB

40% = 48.5GB

25% = 30GB

MacBook Air 13″, macOS 10.13

Available storage space does play into your Mac's overall performance. One area that it does would relate to when your Mac does not have sufficient amount of RAM to hold multiple apps, those apps will be swapped out to your Mac's system drive. If there is not enough space on that drive, it would affect how much can be swapped.


However storage space is only one factor that can affect overall performance. Having slow rotational HDDs vs. SSDs, total RAM available, CPU, etc. would play even bigger roles.
