I have a Dell Optiplex 3020 MT and am aware that there are a total of 3 SATA ports, namely SATA-0, SATA-1 and SATA-2. Also, according to the Dell spec, there is one SATA II port and 2 SATA III ports. Could anyone please advise as to which is which? My HDD is currently connected to SATA-0 and the optical drive linked to SATA-1. SATA-2 not used. Thank you
