which sata port to install optical drives
1) Connecting the SATA power cable. The SATA power cable is an obviously wired cable that comes from your power supply and ends in a thin, black plug. Just plug that into the appropriate place on the back of your optical drive. 2) Connecting the SATA data cable. The SATA data cable is a thin cable terminating on both ends in an L-shaped connector that probably came with either your drive and/or your motherboard. Plug one end into a free SATA port on your motherboard, and the other end into the port on the back of the drive.
