Comparing Write Performance of Double Layer and Single-Layer DVD+R Media
Although mainstream single-layer DVD rewritable drives have now reached 12X to 16X DVD+R write speeds, DVD+R DL media speeds are far behind at only 2.4X to 4X. At the 2.4X speed, it takes about 45 minutes to fill an 8.5GB double layer disc, compared to about 25 minutes at the 4X speed. By comparison, it takes about only 6 minutes to burn a 4.7GB single-layer disc at 16X speed. Since only a few of the double layer drives incorporate 4X as well as 2.4X write strategies, I recommend you check for 4X capability before purchasing. 4X capable drives will support second-generation 4X DVD+R DL media when it becomes available.
