How fast can you read/write data on a Blu-ray disc?
According to the Blu-ray Disc specification, 1x speed is defined as 36Mbps. However, as BD-ROM movies will require a 54Mbps data transfer rate the minimum speed we're expecting to see is 2x(72Mbps). Blu-ray also has the potential for much higher speeds, as a result of the larger numerical aperture(NA) adopted by Blu-ray Disc. The large NA value effectively means that Blu-ray will require less recording power and lower disc rotation speed than DVD and HD-DVD to achieve the same data transfer rate. While the media itself limited the recording speed in the past, the only limiting factor for Blu-ray is the capacity of the hardware. If we assume a maximum disc rotation speed of 10,000 RPM, then 12x at the outer diameter should be possible(about 400Mbps). This is why the Blu-ray Disc Association(BDA) already has plans to raise the speed to 8x(288Mbps) or more in the future.
