The PS3 uses a 2x BD drive, which is 72Mbits/second or 9MB/second. The Xbox360 uses a 12x DVD, which gives it about 16MB/second. What is made up or incorrect?

2x Blu-ray Drive (72Mbps(9MB/s))
Single Layer (2x CLV) - Constant Linear Velocity (Same speed across entire disk)
Entire Blu-ray Disk is read at 9MB/s.
12x DVD-Rom Drive SL (9.25MB/S-15.85MB/s(AVG ~8x(10.57MB/s) DL (4.36MB/s-10.57MB/s(AVG ~6x(7.93MB/s)
SL(DVD-5) 12x Max (5-12x Full CAV) - Constant Angular Velocity (Speed Varies from edge to edge)
DL(DVD-9) 8x Max (3.3-8x Full CAV) - Constant Angular Velocity (Speed Varies from edge to edge)
Speeds vary on DVD drive and can go as high as 9.25 mb or as low as 4.36 mb (dual layer) for 360
consistant speeds across the Blu-ray and can go as high as 9mb for the PS3 (consistantly).
