Excerpt: In terms of a CPU, someone sees a 1.5 GHz CPU, and automatically assumes it to be faster than a 1.3 GHz CPU. We all know thats not always the case - in fact, it can be rather far from the truth. The same applies to hard disks. A less experienced user sees a 60 GB hard disk, and automatically assumes it to be better than a 30 GB drive. Again, far from the truth.
