Yes, but dual-layer writes make the spec, read speed doesn't (only single-layer read speed is listed)

In my experience, dual layer disc average read speeds
read at a different data rate than single layer
discs. Do DL write speeds differ too?

The spec says it's an 8x4x12x DVD.  What do those numbers mean?
My guess:
Reads at 12x speed
Writes at 8x speed
Re-writes (using RW media) at 4x

From what I've seen the speeds are normally shown in decreasing
order: eg 12x/8x/4x.

BTW the "base" speed of DVD is higher than for CD: they physically
spin about 3 times as fast and transfer data 9 times as fast due to the higher storage density. In other words a 12x DVD drive can spin at about the speed of a 36x CD drive and transfer data at the speed of a hypothetical 108x CD drive.

I doubt we'll ever see anything faster than 16x DVD drives as they'd
probably destroy the discs.

Speeds are standardized on writes/rewrites/reads/dual-layer
