This graph shows hardware evolution over time. The vertical axis is in log scale. First, CPU and memory are improving at 50% per year. However, disk is improving only at the rate of 15% per year. And, this gap is widening from 5 orders of magnitude to 6 orders of magnitude. In human scales, back in 1990, if CPU access takes 1 second, disk would take 6 days. In 2000, this ratio is now 1 second to 3 months. Let’s think about that this means. It takes 1 second to grab a sheet of paper and write something down. If you call the Santa Claus to physically mail you a piece of paper, it may take 6 days. It takes about a month to make your own paper from papyrus, and most of the time is waiting for your paper to dry up. 3 months is a long time!
