Blu-ray Recording Speeds
The Blu-ray camp plans to release BD-ROM, BD-R, and BD-RE simultaneously to the market. They are the pre-recorded, recordable, and rewritable versions of the format, respectively.
The Blu-ray specs say that the 1x speed is 36Mbps. Several manufacturers have already announced support for 2x speed. Note that 4x speed is already faster than 12x speed for DVDs, and Philips R&D labs have already achieved 7x recording speed.
Good things are coming for Blu-ray.
