The reviewer appears to have fallen prey to the "RPM myth" which is the belief that faster RPM always equals faster hard drive. Apple and others have pointed out that the new 4200 RPM drives have higher density than older 5400 RPM drives and actually have a higher throughput than the 5400s. I haven't tested this myself, but this claim should have been tested by a reviewer.
