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 statistics except for longevity.
Note:
For more on using MaxIQ in Adaptec Storage Manager, see Configuring the MaxIQ Cache on
page 79 and Logging Statistics for Remote Analysis on page 120. For a list of MaxIQ-compatible
Solid State Drives, see www.adaptec.com/compatibility.
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.
