But definitely not the worst. I burn a BD burner Panasonic UJ-240 in a Dell Optiplex 740 Small Form Factor (housing, AMD Athlon 64 X2 3800+, 6GB of RAM, Win7 64bit, Nero 14) and with a Asus BW-16D1HT in a self's PC (AMD FX-8350 processor (8 x 4.0 GHz), 16GB of DDR3 memory, Win7 64bit, Nero 14) and had so far not a single failure (27 blanks overall, 12 on the Dell).
Movies / Series I burn in principle with 2x speed, even for DVDs I have always used for a slower speed. The examination of the combustion result with Nero DiscSpeed shows an equally good result and therefore a sensible, long shelf life (in light-protected envelope).
Data / Backups are fired with 6x speed, even in the elderly Dell. Here the result is not as optimal as in the movies, but in sufficient quality. For backups that must be stored longer, so I use then also prefer the 2-fold speed, sure is easy safe) and the result much better.
This I had to date not a single blank failure, the firing result is very uniform, the price is to be considered as very low and can also make them on my old computer any problems I recommend these blanks only fully.
Oh, and another note: I may not close all running programs when I burn something, but I'm making then some coffee or something else - definitely not the way I work on the computer.
