You guys are brutal. Did you ever think the author of that might be lurking around from time to time:)
The article wasn't just written on a whim, the author spent a couple of months playing around with different settings. As for System Restore, you will see a speed increase on any HDD or SSD. The thing with SSDs when that article was written was that you didn't want to go around thrashing them with random writes all of the time. We were really still trying to understand TRIM at the time. Also, TweakTown is written mainly for enthusiasts but we do get some regular traffic too, err I mean they might get some regular traffic too. That is why all of the risky stuff is labeled as such. Anyhow, I spent a lot of time getting that list together and have mounds of first hand data from testing.
Err I mean someone must have mounds of data:)
