I am wondering how fast the current 2011/2010 era macs spin the optical media. I'm talking about real physical speeds even if it is complicated.
Angular velocity is fine, linear velocity is fine - the radius is fixed, so the math is easy.
If you can address both slot load and tray loading or go into details how the speeds vary, that would be very nice.
I am also curious of the read speed is different than the burn speed for writeable media of the various types.
Some times you can specify 1x or 8x - but don't know what is the "normal" burn speed. My understanding is they employ zoned constant linear velocity (ZCLV) but I don't see a good reference for hardware that is shipping presently that goes into any detail what 8x actually means.
