SSD vs HDD Costs

Facetting a line graph.

The original line graph


My redesign. A faceted line graphic.

Since the SSDs are being compared with HDDs, I think faceting the graphic so that each facet compares a specific SSD type (128GB, 256GB) with the “baseline” HDD price emphasizes the comparison better.

The story being told in the paper is “While SSDs are still more expensive, the price is dropping significantly, while the price of HDDs has stabilized in the past years.”
