03-10-11: PerrewAfter reading it (the article on the lower half of the page) several times, I must say that I have very little idea of what he is saying :-)
Here is an interesting take by someone saying SSDs cant improve sound....
I think that one of his main points, though, is essentially that noise produced as a result of activity of the cpu chip, under software control, is the predominant source of internally generated noise in the computer. The reason being that it draws more current than any other device in the computer, and rapid fluctuations in that current (which are primarily responsible for the noise generation) will be greater than for all of the other devices in the computer, including the digital chips in the SSD or HDD (an HDD has significant digital circuitry, in addition to the electromechanical stuff). He appears to conclude, therefore, that all internally generated noise that is not produced by the cpu chip, and all other effects that may be caused by the rapid switching of digital signals elsewhere in the computer, is insignificant.
As someone with extensive experience designing high speed digital circuits (not for audio), that all strikes me as meaningless oversimplification, of things that (due to their complexity) are inherently unpredictable apart from experimentation.
