Just got it this week. I was expecting a Plextor but got an
Optiarc AD-7170A. Research shows that Optiarc is a joint venture of Sony Nec but it is a weird drive and no other programs recognize it so I can only use it with Microstudio so even though it should burn DVDs I can't because my DVD burning software package won't recognize it. It wasn't until after I printed my bill that I saw the words "for the drive to work, you will need Microstudio or Hoster software from MTU. Too late to cancel at that point so I hoped that must meant for karaoke, not that it wouldn't work with anything else.
So.....if you need a drive for things in addition to MTU products don't get this drive. Find a used plextor or one of the more common name brand drives that will also work with MTU programs. This was an expensive lesson for me cause even if they take it back (which I have requested) I will be out postage both ways and a 20% restock fee for a total of about $41. I would much rather have spent that money on program upgrades.
