Identify data available on a drive's SMART interface
identify fields to add to Benchmark object
identify how to display information
implement solution for Windows, Mac OS, Linux
The SMART (Self-Monitoring, Analysis, and Reporting Technology) interface of an SSD (Solid State Drive) provides valuable data for monitoring the health and performance of the drive. Some of the most useful information you can get from an SSD's SMART data includes:
Total Bytes Written (TBW): This indicates the total amount of data that has been written to the SSD. It's important for understanding the wear and tear on the drive, as SSDs have a limited number of write cycles.
Wear Leveling Count: SSDs use a process called wear leveling to distribute write and erase cycles across the memory chips evenly. This metric shows how effectively the drive is managing wear leveling, which is crucial for its longevity.
Bad Block Count: This shows the number of bad blocks on the SSD. A high number of bad blocks can indicate a failing drive.
ECC Error Rate: Error-Correcting Code (ECC) errors occur when the data read from the drive doesn't match what was expected. A high ECC error rate can signal a problem with the drive's reliability.
Program Fail Count / Erase Fail Count: These counts show how many times the drive has failed to write or erase data. Repeated failures can be a sign of a problem with the drive.
Power-On Hours: This tells you how many hours the drive has been powered on. It's a basic measure of the drive's age and usage.
Drive Temperature: Overheating can significantly shorten an SSD's lifespan. Monitoring the drive's temperature can help prevent damage due to excessive heat.
Uncorrectable Soft Read Error Rate: This indicates the rate of read errors that could not be fixed by the ECC. A rising rate can be a sign of deteriorating reliability.
SMART Error Log: A record of all errors logged by the SMART system. It can provide insights into intermittent issues that aren't necessarily captured by other metrics.
Remaining Life Percentage: Some SSDs provide an estimate of the remaining lifespan of the drive. This is calculated based on the drive's usage and wear.
