There is an excellent HD benchmarking program called HD Tach and is
available at http://www.simplisoftware.com/Public/index.php?request=HdTach.
They have a large list of benchmarked drives so you can see how well your
drive compares to those listed. Compare performance for random access, or
sequential reads/writes. It is a must have if you need the fastest drives
possible. They have a free version or a registered version.
