In any SMART monitoring program, you should see attributes that contain at least some of these fields: Also, they don't explain which of the various attributes or variables are worth our attention, making us drown in data.īefore attempting to understand which SMART attributes are relevant, we first have to differentiate between the main types of SSD and HDD failures: predictable and non-predictable. For example, some manufacturers store power on-time data as hours, while others measure it in minutes or seconds.

Still, there are many inconsistencies in the statistics because many of the hard drive manufacturers use different definitions and measurements. The system provides a great deal of internal data. However, know that, apart from some singular attempts ( Google, Backblaze), most of the S.M.A.R.T. If you want to get an in-depth idea of all the SMART attributes, as there are about 50 of them (raw read error rate, spin-up time, reported uncorrectable errors, power-on time, load cycle count, etc.), visit this webpage. SMART keeps track of a series of variables whose number and type vary from drive to drive, which are indicators of its reliability. 🙂 What it does is an entirely different story, though. How does SMART do that? You might be tempted to think that SMART can magically guess if your drive is healthy. That means, plainly speaking, that SMART should supposedly be able to tell you if your hard drive or solid-state drive is about to stop working!ĭrive health information is provided by SMART SMART was invented because computers needed something that could monitor the health state of their hard drives. It is independent of your operating system, BIOS, or other software. SMART, also written as S.M.A.R.T., is a technology found inside HDDs and SSDs. Its clever name is actually an acronym for Self-Monitoring, Analysis, and Reporting Technology.
