    Maximum formatted capacity
    CD-Rs come in 650MB or 700MB formatted capacities, and virtually every CD burner can handle either. Because they use special formatting, CD-RWs top out at 530MB. Today's DVD burners generally write up to 4.7GB on a single-sided DVD-R or DVD-RW and up to 9.4GB on a double-sided disc. DVD+RW drives currently use single-sided 4.7GB discs. DVD-RAM drives work only with cartridges that hold double-sided discs capable of storing up to 9.4GB.
