Examples 1) A SATA II device on a SATA II port = SATA II speeds and a SATA III device on a SATA III port = SATA III speeds on the same motherboard. 2) A SATA II device on a SATA II port = SATA II speeds and a SATA III device on a SATA II port = SATA II speeds on the same motherboard. 3) A SATA II device on a SATA III port = SATA II speeds and a SATA III device on a SATA III port = SATA III speeds on the same motherboard. Basically, the drive will run at the SATA controllers speed, be it SATA II or SATA III, along with mixed controllers being used. Can't find your answer ? Ask !
