The values appear to originate from an intrsinsically flawed test setup. Just take the first test. The database has to do 1000 commits. That means 1000 I/O operations. There is no way that a 7200 RPM disk can do that in the time that that test says it took. It is reasonable to say that a disk can do 1 I/O operation per rotation, which means that any test result below 9 seconds is untrustworthy.
