Yeah. 40X. Right. Maybe saves 20sec/CD over the 32X model.

These things work on a "zone" basis, using 16X for maybe the first 1/3 of the disc, then 20X,24X,28X,32X,36X,40X (two or three of those) on the remaining fractional portions ("zones"). Average real-life speed oughta be in the 20s. The 16X burners use 16X for the entire disc.
