Yes...be smart and understand that the thread is no more than personal opinion on behalf of the OP. Many of the items he critiques are backed up not only by other sites but by Microsoft and Intel as well (ie Disabling Superfetch). If you are looking at crunching your numbers, there is an article here that discusses alternate methods of storage as well as a guide here that will explain methods as I described above. The latter guide is supports by several SSD Optimization and tweaking sites throughout the internet.
Your best option is to seek advice from a trusted source who can not only speak through knowledge and education but also through use of the methods suggested. You will find LOTS of people who will tell you how bad something is having never personally tried it themselves.
After all, the world was once believed to be flat right?
