What is S.M.A.R.T. and How Does it Work?

Previous  Top  Next

S.M.A.R.T. is an acronym for Self-Monitoring, Analysis and Reporting Technology, an open standard for developing disk drives and software systems that automatically monitor a disk drive's health and report potential problems. Ideally, if a problem is reported, you have enough time to take proactive actions to prevent impending disk crashes.

A S.M.A.R.T. drive monitors the internal performance of the motors, media, heads, and electronics of the drive, while our software monitors the overall reliability status of the drive. The reliability status is determined through the analysis of the drive's internal performance level and the comparison of internal performance levels to predetermined threshold limits.

How does S.M.A.R.T. Work?
Part of what makes the S.M.A.R.T. system possible is that disk drive reliability has been intensely studied for many years. Manufacturers spend billions of dollars researching how vital areas of disk drives change over time, and operating environments. By analyzing this data, they can define performance thresholds, which correlate to imminent failures.

SMART Disk monitor turns on this capability, interacts with it, and reports these conditions to the system administrator. Although the specific parameters
