What is SMART?
Normally, there are only two kinds of hard drives: those that have failed and those that are going to fail. Many users wonder how to discover the signs of the hard drives failing. Actually, there is an excellent feature you can apply to monitor the hard drives of your PC or Mac, that is, SMART.
SMART, also known as S.M.A.R.T., is the abbreviation for Self-Monitoring, Analysis, and Reporting Technology. It is a monitoring system included in computer HDDs, SDDs, and eMMC drives. The primary function of SMART is to automatically detect and report various indicators of drive reliability with the intent of anticipating imminent hardware failures.
In other words, SMART should spontaneously tell you if your HDD or SDD is going to stop working.
