So far the unit reads all discs I have tried but its spinning makes a lot of noise at max speed; this is correctable by nero drive speed; however copying a full DVD takes around 10 minutes to complete; writing is unexpectedly good, being able to burn 8x CAV some rebranded prodisc R03 tuffdisc +R media, that proved to have low error rates and smooth reading curve also on other drives. Recognition time is also good around 10s. So far I wrote a Verbatim CD-R at 24x CAV with good results, playing flawlessly on my VDO car mp3player. The unit is not supported by the Nero CD speed PI/PO scanner, you have to test the media on another drive. Verbatim +R 16x media seems to be unsupported, the burn locks up with Nero 7 but the disc is left unharmed. So my firsts impressions about this drive are good.

CLV = Constant Linear Velocity, the DVD is written at a constant speed. ZCLV = Zone Constant Linear Velocity, the DVD is divided into zones. After each zone the write speed is increased. PCAV = Partial Constant Angular Velocity, the DVD is being written at an increasing speed until a certain speed. After this speed it will not increase anymore.
