While the processor speed may look slower, that's simply the "base frequency", which is like the idle speed in a car engine. If the work requires it, the processor can automatically speed itself up all the way the 4.2 GHz. Because the performance of the hard drive is really independent of the speed of the computer, the performance of this hard drive compared to yours should be about the same.
