@ Fumanchu: For one, you can't expect all of the commonly used assets at the outer edges of a DVD... unless the game is incredible small. For two, mandatory install on multi-plat games doesn't prove that the bluray drive is slow, it shows that the game was ported over, and the harddrive was taken advantage of so that the programmers wouldn't have to actually put work into the port. Try looking at exclusive games, if they all needed installs then maybe it would mean the drive is slow, but they don't. And for three,
"2x Blu-ray Drive (72Mbps(9MB/s))
Single Layer (2x CLV) - Constant Linear Velocity (Same speed across entire disk)
Double Layer - Couldn't find any data but no games have been released on a double layer yet.
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
Majority of 360 games are on DVD-9."
this come from here: http://forum.beyond3d.com/showthread.php?t=42157
To sum that up, yes the 360 has a 12x drive, but most games need the dual layer space in a DVD-9, which runs at a max of only 8x which goes from 4.36MB/s to 10.57MB/s. The max speed still beats the max of 2x bluray, which is 9MB/s, but comparably, the bluray is by NO means slow.
@bdbdbd: See above regarding the drive speeds...
