Yup, Peter Blaise should change his nick to Gish Gallop. I'm pretty sure that SSD's do their own refreshing. Yes, and more intelligently. They don't at random refresh or refresh everything, they keep track of what data is most at risk and refresh only that. Because as you say the drive would otherw...

Now granted I did so to anyone making some statement about SR having super-low access to the drive, or secret patterns, or worst case scenario patterns etc., not per s...
