HD Tune Benchmark Results

Comparison Chart: When comparing the Seagate Momentus 7200.3 to other popular hard drives like the Western Digital Scorpio Blue 500GB and the Seagate Momentus 7200.2 200GB, you can see that it dominates the performance tests.  One thing that should be pointed out is the temperatures observed while testing the hard drives.  The Seagate 7200.2 and 7200.3 hard drives operate at 7200 RPM and as a result are much hotter than the 5400 RPM Western Digital Scorpio Blue as you can tell from the chart above.
