The Smartmon Tool
You can use a software tool — Smartmon — that monitors three Self-Monitoring, Analysis, and Reporting Technology
(SMART) attributes for SSDs. Smartmon includes a command line utility, smartctl, used to check these attributes.
Obtaining the Smartmon Tool
The Smartmon tool is available from the following sources:
• From Intel as part of the “Intel Solid-State Drive Toolbox” at http://downloadcenter.intel.com.
• From http://sourceforge.net/apps/trac/smartmontools/wiki.
NOTE: Use the latest version of the Smartmon tool with the Intel 320 Series SSDs.
SMART Attributes
The three primary attributes measured by the Smartmon tool are:
• Workload Timer ID E4h — Time elapsed during the current workload.
• Timed Workload Host Reads Percentage ID E3h — Percentage of I/O operations that are read operations during
the last workload timer loop.
• Timed Workload Media Wear Indicator ID E2h — Drive wear during the last wear timer loop, as a percentage of
the maximum rated cycles.
NOTE: You must run the workload to be evaluated for at least 60 minutes for these SMART drive attributes to
register.
Smartmon Tool and smartctl Resources
For details of the Smartmon tool, the smartctl utility, and SMART attributes, refer to:
• “Intel Solid-State Drive 320 Series in Server Storage Applications” and “Intel Solid-State Drive 320 Series
Enterprise Server/Storage Application Product Specification Addendum,” available at http://
