The inquirer specified that the technology must accomplish these tasks without disrupting the data on the drive or causing additional damage. The inquirer requested information on technologies that can, without operator action, assess the health of SSDs to measure performance and predict potential failures. The unexpected and unpredictable nature in which many SSDs fail may necessitate additional measures, like more frequent backups, scheduled early drive replacement, built-in redundancy, and/or use of drive array configurations that can automatically rebuild a failed drive. When considering employment of SSDs in critical Department of Defense applications, DSIAC found that health-monitoring tools likely do not provide the necessary risk mitigation. Some of these factors could be mitigated by matching a manufacturer’s SSD to the health-monitoring tools they developed to monitor it. The possible lack of environmental sensor data.

The possible lack of error logs for assessing past performance.

The failure of some manufacturers to fully disclose what their SMART attributes are or specifics in data they report.

Discrepancies in how different manufacturers define their reported SMART attributes.

Loose industry standards for determining SSD reliability and reporting of SMART attribute data.

Additionally, other factors, such as the following, bring into question the accuracy/reliability of the reported information on SSD issues, especially when using second-party utilities: However, for critical applications, these tools are of limited use in predicting the date or time an SSD will actually fail. The tools generally provide a conservative notification that allows the user to replace the drive prior to losing data integrity.

This information was provided to the requester.įor normal consumer and many industry applications, DSIAC found that both the OEM and second-party software health-monitoring be used to continually monitor and automatically send notifications about SSD issues. DSIAC also reviewed information on SSD reliability and software utilities provided by original equipment manufacturers (OEMs) or second parties for SSD health monitoring. The Defense Systems Information Analysis Center (DSIAC) received a technical inquiry requesting information on technologies that can, without operator action, assess the health of solid-state drives (SSDs) to measure performance and predict potential failures.ĭSIAC staff reviewed information found using the Defense Technical Information Center Research and Engineering Gateway and open sources on to Self-Monitoring, Analysis, and Reporting Technology (SMART) embedded in modern computer storage media devices and their control electronics.
