SATA II / III Cables, Connectors and Components (DVD drive, HDD)

This is my DVD drive which I assume is SATA II, correct?:

And this HDD is SATA III since its transfer is 6 Gb/s, right?:

So here's my main question: my motherboard (ASRock Z77 Extreme4) came with SATA III cables and has both SATA II and SATA III connectors. To get the best speed from my HDD I should plug it into the III connector, but what about my SATA II DVD drive with SATA III cables? Does it matter, what would you recommend?

Thanks for the help.

    The cables are backwards compatible and hardly any SATA II cables out there that can not transfer at SATA III speeds. Hook the HDD to the SATA III connector, although no mechanical HDD can max out the SATA II interface, but the DVD to SATA II.

    You can't really max out a sata III w/ a HDD. But it should perform optimally using a SATA III connection.
