Old vs. New and Comparison Table

We summarized the improvements of the Hitachi Deskstar 7K1000.B over its predecessor 7K1000, and the performance difference between the Western Digital WD1000FYPS and the new WD1001FALS. Please consider that in case of the WD drive, we’re comparing 5,400 RPM with 7,200 RPM, while Hitachi made a step from five platters to three platters, doubling the total capacity. WD has had a 750 GB Caviar drive, which might as well be the one to compare.
