I don't know about the latest offering from Samsung. But, I wouldn't buy a Samsung optical drive, even if it was a sole seller in the market. In a year's time most of them start giving a problem with the tray or stop reading CD/DVD.
Just search around the forum, you will get 'n' no. of threads where people are cursing Samsung drives.
I don't recommend Samsung CD/DVD writers. Most of the users are having problem in mechanism of tray operation. Samsung is doing well only in Monitor business.
