I bought a Mac Mini (Intel CPU) about two years ago, and its disk "percentage used" is already 12%, and there are 160TB write (and 150TB read). Compared with other programmers, seems that mine is a little bit too much - many are only one third / half / even smaller compared with mine.
Therefore, I wonder:
- Is this normal or abnormal?
- What should I do to improve the situation?
More information (not sure whether this is related):
- CPU is intel i7
- Memory is 32GB
- Usually see a
- The only usage is to do programming, no games, video-cutting, etc
