Hello,

Best practice is to set the BIOS SATA mode to AHCI when using a single SSD to support the TRIM command in Windows.

However, I am using a RAID controller to RAID1 a pair between 2 HDD's. But in addition to that, 4 SSD's will be attached to the same SATA/RAID Controller.

Setting the BIOS to RAID makes sense, but will the TRIM command still pass through to the 4 unRAIDed SSD's?

Thank You


PS. Not using Intel board/chipset, am running AMD Opteron. Read that Intel recently released drivers that pass through the RAID controller. Maybe AMD has it also?

You'll have to check with the mobo OEM and maybe AMD directly, to see if the TRIM command passes through to the unraided SSDs.

Any drives that are not part of a RAID array will automatically default to AHCI mode, so the TRIM command will pass through.
