4.1SMART Technology
The MegaRAID Self Monitoring Analysis and Reporting Technology (SMART) feature detects up to 70% of all predictable drive failures. SMART monitors the internal performance of all motors, heads, and drive electronics. You can recover from drive failures through online physical drive migration.
