Quantifying the value of today's SSD goodness
 

Value comparisons have become a bit of a tradition here at TR. We rolled out our first CPU value article way back in 2007 and followed up with a second look a year later. A quantitative assessment of the value proposition has since become an integral part of our CPU reviews, and we've even considered the value of graphics cards. What can I say? We loves us some scatter plots.

So should enthusiasts. A quest for the best value is deeply ingrained within the community's collective psyche. We're interested in getting the best bang for our buck—finding the proverbial sweet spot that delivers the fastest possible performance at a reasonable or at least justifiable cost. Our value scatter plots tackle performance and price at the same time, neatly mapping a landscape that we can then scour for the best combination of those elements.
