Re: IDE ATA/ATAPI controllers not showing up, unable to TRIM SSD
The “optimization” option you are talking about doesn’t refer to TRIM support, it actually enables a SSD to work as a caching device. Probably the reason why you can’t enable it is because you installed the OS in the SSD, therefore it cannot be used as caching device. (This option is often used for mSATA drives instead)
To check if your SSD is using TRIM you can download HWInfo64 and check the features that are enabled for your drives.
