In recent day's popularity of the Internet and storage has increased in multiple folds. For today's world minimum requirement for storage is reliability and cost efficiency. The backbone of the mass storage is the hard disks, which finally preserves the data. So considering the cost, performance and availability, there are different kinds of hard disks available. However, the reliability and data availability from the hard disk is a crucial aspect. This paper describes an efficient and novel approach to select the hard disks from the bunch/pool of hard disks of different types so that the data will be preserved safely with high reliability.
