| Sqrl said: FYI - The diameter of the data holding section of a DVD is 116mm outer and 44mm inner. This means that the total area for data storage is aprox 36,200mm². Of that area ~15,680mm² is in the outer 1/3rd of the disc where it spins the fastest. In other words aprox 43.3% of the data is available at the highest speeds. |
Your basic argument is true, but the way it is worded gives something of a false impression. You make it sound as though 43.3% of the data will be read at the fastest speed, which is obviously not the case. It is true that the mean average speed will be higher than the median though.
Data can be pulled from a 12x DVD at a Constant Angular Velocity faster than it can from a 2x BD at Constant Linear Velocity, but the 360's drive can only read dual-layer discs at 8x, giving the advantage to the PS3's BD drive. The DVD drive's top speed will always be higher than the BD drive's though, so both systems have their advantages and disadvantages.
