What is the recording speed for DVD+R and DVD+RW?
Every DVD+R/+RW drive can write both DVD+RW as well as DVD+R media at least at 2.4x DVD speed (comparable to 22 Mbit/sec or 20x CD speed), as 2.4x is the minimal writing speed for DVD+R and DVD+RW. For DVD-R and DVD-RW, the minimal writing speed is 1x DVD, you need certified discs and a capable recorder to write at higher writing speeds. Most recent DVD+R/+RW drives will write at certified DVD+R media at 4x DVD speed, while newer drives will also write certified DVD+RW media at 4x DVD speed. This makes DVD+RW the fastest rewritable DVD format around.
