Chapter 8: Maintaining Physical Devices ● 90 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 on page 78 and Logging Statistics for Remote Analysis on page 119. For a list of MaxIQ-compatible Solid State Drives, see www.adaptec.com/compatibility.
