 For larger quantities of 100,000 units, the 30 gigabyte HD DVD was more expensive than the 25 gigabyte Blu-ray ($1.55 versus $1.49).While there is a HD-DVD variant that acts as a successor for the DVD-RAM, the HD DVD-RAM, a "“BD-RAM”" has never been released.Although the BD-RE has unrestricted random writing access capabilities, its rewrite cycle count of around 1000 times is much lower than the potential 100.000 rewrite cycles of some DVD-RAM variants.
