Sometimes, there is a lot of activity on my Macbook Pro drive, and I would like to find out what is causing all these Disk I/O’s. I found this thread that can help:

There are two suggestions on that thread. Either using ‘iotop -C 5 12' or using 'fs_usage'.

What I would like to find though is a tool that would analyze my Mac’s resources over a full day of work and that would report what should be tweaked. I don’t know if such a tool exists though. I you know of one, please let me know.
