What is the difference between HDD Health, Health/Performance, Performance and Information attributes?

Health shows a probability of hard disk drives normal functioning. Performance shows what is the disk's performance compared to the reference one as specified by a manufacturer (as the number of search errors and substituted sectors increases the performance drops down).

Health/Performance combines the first two attributes. It says that decreasing of disk performance correlates with the risk of failure.

Information is not considered an important attributes by a HDD manufacturer. Even if it reaches the critical value, the performance and reliability are not diminished.
