I picked up one of these a few weeks ago principally for CD audio extraction. It didn’t perform as well as the old drive a Sony 7240s. I had a look at the chipset and found they are now using a Renesas MC-10131 chipset. I haven’t done any CD / DVD burns yet, but it certainly isn’t the CDDAE drive the old 7240s was.
I see all of the discussions relating to * Optiarc, is occurring in forum 86. If a kind moderator would move this to the correct thread it would be appreciated.
