I donÂ´t think there is the [B]one[/B] best blu ray optical drive for data recovery.
As always, it depends on the application You are using it mostly for.
You will be able to find the best drive for a certain BR mediacode, but not for any mediacode.
Lately, I was impressed by the mechanical properties and quality of the Pioneer BDR S08XLT drive. It is better than the BDR208xxx drives I have, even the writing quality of some BR medicodes is better with the BDR S08, though it has basically the same firmware as the BDR208.
I canÂ´t tell if that is the result of the better mechanical quality or if itÂ´s just serial spread, or if it is the best reader for Your purpose.
Maybe, some of the older BR drives were manufactured with more diligence than the new ones.
For example, the LG BH16NS40 is a rattletrap in comparison to the Pioneer drives.
It still performs excellent with some selected BR mediacodes, but for how long…
