The combined throughput diagram shows that there have been considerable performance jumps from one drive generation to the next. We've observed similar results when comparing a Samsung Spinpoint F1 with the F2, looking at Seagate's Barracuda 7200.11 and .12, and when testing various WD Caviar generations.
