Working with Solid State Drives
You can use Adaptec Storage Manager to check the status of the SSDs in your system. You can
use this information to verify the health of your SSDs and to predict drive failures.
For MaxIQ-compatible SSDs, Adaptec Storage Manager displays SMART statistics for the drive
using Self-Monitoring, Analysis and Reporting Technology. It also displays wear-level and
longevity indicators. For non-MaxIQ-compatible SSDs, Adaptec Storage Manager displays the
same set of statistics
except
for longevity.
Note:
For more on using MaxIQ in Adaptec Storage Manager, see
Configuring the MaxIQ Cache

page 78
and
Logging Statistics for Remote Analysis
on page 119

Solid State Drives, see

To view the SMART statistics for a SSD, select the drive in the Physical Devices View, click the
Properties
button, then select the
Smart
tab. To view wear-level and longevity indicators for
the SSD, select the
Status
tab.
