Full-Steam-Ahead DVD

Today's conventional DVD burners can deftly handle writing two layers of data onto a disc, and they can do so significantly faster (by nearly a third, if you pick the right drive) than they could just six months ago. In recent months, drive manufacturers have increased the write speeds of dual-layer DVD-R and double-layer DVD+R burners from their original speeds of 2.4X to 6X and 8X, respectively; and each type should eventually hit the same 16X maximum write-speed ceiling as write-once single-layer DVD drives.
