No advantage. Read writes speeds for blu-ray drives are so low compared to even the throughput of sata II that there will be NO increase in performance. Have five blu-ray drives, Three in laptop only read blu-ray and write DVDs, the two in my desktops are both blu-ray writers. Even the so called sata 6 HDD benifit VERY little from sata III, only burst speed is higher, and HDDs are much faster than dvd/blu-ray medium.
