Clear The Cache Of Solidigm™ QLC SSDs

Summary

• Solidigm Client SSDs that have Quad-Level Cell (QLC) have a built-in cache, to boost their performance.
• If such a drive is having performance issues, clearing this cache may help its performance.

Clearing the cache can be done with the GUI or CLI versions.

• GUI will only let you clear the cache.
• CLI will let you view stats about the cache, as well as start/stop clearing it.

Toolkit GUI

NOTE: Although the cache-clearing feature is in the Fast Lane tab, it does not imply that Fast Lane is supported for every Solidigm Client QLC SSD.

Launch the "Solidigm Synergy™ Toolkit". Locate the correct SSD, in the "Drives" tab. Select the "Fast Lane" tab. Click the "Clear Cache" button. The button appears if supported.
