Btw. 2x speed on BR is equal to 8x speed on DVD and 32x on CD.
That's incorrect. A 2x Blu-Ray drive (25 and 50 GB) rotates slower but reads more data per second on average (6.8 GB Dual Layer) 360 DVD.
Regarding read speed 2x PS3 Blu-Ray vs 360 DVD:
"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)
SL DVD is 1.57MB/s > SL Blu-ray
DL DVD is 1.07MB/s < SL Blu-ray
Majority of 360 games are on DVD-9."
