DVD+R Dual-Layer Write Performance
While Plextor surprised us with a performance drop in dual-layer Blu-ray recording, Asus takes a hit in dual-layer DVD projects.
Again, we see that a drive is supposedly operating in CAV mode, but appears to have a CLV write pattern.
LG’s SATA interface does well, reaching the 8x limit observed in most writers for our dual-layer media, and achieving a 6.96x average.
Plextor actually reports that it’s writing in CLV mode, though it’s 6.26x average is only marginally below LG’s CAV performance.
Dual-layer DVDs demonstrate no performance changes for either LG or Plextor in the transition from primary to secondary PC interfaces.
