I can't find specs for the exact drives in the 360/PS3, but seek times for generic drives are easy to google. Seek times for a 12x DVD drive seem to be in the 100ms-120ms range, while 2x Blu Ray is around 350ms. (In other words, DVD seek times are 3-3.5 times faster than Blu Ray.)

Also, what is this about Uncharted having no load times and streaming all data? I have nothing against the game, and it'll be the first one I buy if/when I get a PS3. But the part I played at a friend's house had plenty of loading. Sure, the word "Loading..." never popped up on screen. But every time a pointless and unskippable cutscene plays, that's a load time. Drawn-out scenes showing a doorway closing behind you as a door opens in front of you - that's not even a well-hidden load.

there you go, I believe the blu-ray is in general slower doe to the CLV technique of reading disks (in that the motor has to slow down when reading data near the edge of the disc). Of course, seek times are also dependant on the amount of physical movement required of the read head, and to move over a large chunk of data a blu-ray read head would not have to travel as far. These things are never quite as clear cut as they seem.

However, even though the numbers may vary, it would take incredibly bad design to make the Xbox360 load the same data slower than the PS3 directly off the disc.

 

That is partly to blame. According to the guys at Beyond3D, the ps3's Blu-Ray drive reads dics at a constant 9 mb/s, while the 360 drive reads dual layered DVDs at a maximum of 10.57 mb/s and a minimum of 4.36 mb/s (averaging out to about 7.93 mb/s).  Even though the 360's drive speed is lower on average, because it is faster at times, developers can put the more important data on the outer edge of the disc, so that it makes use of the faster read speeds, something that they cannot do with the ps3.  The 360 drive's lower seek times help out as well.

@blizzid: Oh c'mon. So it loads during cutscenes.  There are still no pauses in the game at all.  It goes straight from gameplay, to cutscene, back to gameplay.  And there are also long stretches of just gameplay, like the demo on the PSN for example.  And I can't really think of any drawn out cutscenes.  

I mean, you're totally missing my point with that one. Most games have cutscenes AND actual loading screens. Uncharted has no visibile loading at all.  Name a game that does it better.
