I have tried their stuff. It's not cheap, but it works. The surprising thing to me was how much noise hard drives make. Once I had the quiet power supply in place, the hard drives were suddenly very loud. Then I put them into the enclosures (not an easy job) and the whole thing is now quiet enough that I can sleep in the same room with the computer on.
Magnesium chloride is not toxic or particularly hard to find. But it is also not paramagnetic, and as far as I know does not form a tetrahydrate. I supect what the article was supposed to say was manganese chloride tetrahydrate.
