Fast and trouble free installation. A single USB port is enough to feed it (even burning mode) unlike external drives of previous generations for whom he had 2 jacks. Anyway the supplied cable (mini USB - USB) has only a single USB port to connect to PC. As for the Blu-ray burning, 10 pictures were engraved on only 2 disks Verbatim BD-R 25GB legacy (without the LTH technology a priori somewhat maligned). I have deliberately not used the maximum speed: 2 hours to burn and verify a disk with Nero 9. This is long but safe, so I'm fine :)! Playing movies on Blu-ray was no problem with the combination VLC + AnyDVD HD. Same for DVD zones 1 and 2. In conclusion, a good little writer, aesthetically really pretty (in white anyway), and technologically perfect.
