IMHO you shouldn't do it in a grid, it's confusing as a graphic and in some cases results in wrong representation of the data (which every graphical representation of data should avoid), for example, outliers can be too close to "normal" data, distance between two points is not representative of actual variables variation (sorry for alliteration), overlapping points seem to be different and you can't infer a drive price/cost to be better than other unless they share one coordinate(the worst, because that's the purpose of the graphic) I'd say your points need to be smaller or you need to use less points in order to represent your data correctly. I'd like to see a line representing the 1$ per GB ratio and other one representing the mean ratio
