By the time 52x BD burners come out, we’ll be living on Mars. Do you have any idea how fast a BD would have to spin to get up to 52x speed? That’s right, a lot. We’re talking ludicrous speed.
Just to give you an example, here are a few statistics:
1x BD ( 36 Mbps) = 833 RPM
12x BD ( 432 Mbps) = 10,000 RPM
52x BD (1,872 Mbps) = 43,316 RPM
