They allow you to specify where to place the PP, this is because accessing to different location on the disk plate give you different speed. I think accessing the outer edgeis the fastest, I can't remember exactly. It allow you to place your most frequent access data on the fast location. But this may not be applicable any more because the disk technology had improved over the years. In older day, it make sence because you don't have many disks in a system, typically people buy one big disk can cut it out for different usages. Nowaday, people prefer many smaller disks to make up a pool, especially for database access.
