Detailed Explanation

S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology; written as SMART) is a system for monitoring and early detection of errors of storage media such as hard disks or SSDs.   Most hard drives and SSDs have SMART functionality. However, the data provided by SMART, (SMART attributes), are different from manufacturer to manufacturer. There is no "approved" list of S.M.A.R.T. attributes and their per-vendor interpretation. howevern, it is valuable to look at the Smartmontools source drivedb.h header file

Attribute values can range from 1 to 253 (1 representing the worst case and 253 representing the best). Depending on the manufacturer, a value of 100 or 200 will often be chosen as the "normal" value. Manufacturers that have supported one or more S.M.A.R.T. attributes in various products include: Samsung, Seagate, IBM ( Hitachi), Fujitsu, Maxtor, Western Digital. the Wikipedia page for S.M.A.R.T. has more detailed information for reference.
