If you could speed test data through the drive's internal cache
only (something it whizzed through, and didn't need to read or write to
the internal storage medium), you might find you get close to
idealistic claimed SATA speeds.

The other thing to consider with drive thrashing, that I don't recall
seeing being mentioned in this thread is a drive with errors.  If it's
having trouble reading/writing its media, performance will be awful.
