> SSD Disk Cache Policy

> The MegaRAID firmware provides support to change the write-cache policy for SSD media of individual physical drives.

> The MegaRAID firmware does not allow any user application to modify the write-cache policies of any SSD media. The host applications can modify this property through a new logical device (LD) addition or a LD property change. When SSDs are configured in a mixed disk group with HDDs, the Physical Device Write-Cache Policy setting of all the participating drives are changed to match the SSD cache policy setting.
