What is S.M.A.R.T. in disk monitoring, and what does it provide?

• A. It is a CPU temperature monitor.
• B. It is a network protocol.
• C. It is Self-Monitoring, Analysis and Reporting Technology that provides health indicators of storage devices and can warn about reallocated sectors.
• D. It is a memory testing tool.

Answer: (C)

S.M.A.R.T. is Self-Monitoring, Analysis and Reporting Technology embedded in most storage devices that watches health-related attributes such as error rates, spin-up time, temperature, reallocated sectors, and read/write errors. It analyzes those traits over time and can warn you if the likelihood of drive failure is increasing, for example when sectors are being reallocated to spare areas, which indicates growing media damage. It’s not a CPU temperature monitor, not a network protocol, and not a memory testing tool, which is why the description focused on monitoring storage health and signaling potential failure is the best fit.
