A summary from my perspective based on discussions.
Early XBox 360 drives were slower 12x drives, later 360 drives are faster and 16x drives are in use on the 360 today.
The inner most part of a 360 needs to be dual layer, is read first and includes video files and other stuff. The drive rotation speed remains constant across reading discs, thus data at the outer part of the disc is read faster than the inner parts. 360 games are thus optimised to place read speed critical data at the outer part of the disc (but thus involves higher seektimes and more layer switching, as normally a disc is read from the inner parts towards outer parts).
There are many early XBox 360 games which only use a single layer for game data storage, this as layer switches (these delays are different from normal seek times involved with lens movement) aren't involved, thus single layer game data can be read faster.
Games on dual layer discs read data slower due to these layer switches. Generating an image file most likely just involves one layer switch, layer 1 is read and copied then layer 2. This is different from game data reading which involves lots of layer switching. |
Apart from just saying it what concrete information do you have that they're 12x SL drives?
I've seen this disputed - do you have any sources that claim this? I mean apart from 3.4GB install sizes, which doesn't mean the disc uses DVD-5.
I'd love for you to prove everyone wrong but we need something more substantial than 'because I said so'...what I'm asking in case it wasn't clear before is can you provide any proof to your claims?

The information is weird. It doesn't line up. This is what we have so far.
- Some say 12x DL-DVD read speed. Some say 8x DL-DVD read speed.
- The HDD ripping process is STILL different from the two options above (6.6GB in 09:47secs suggests around 16x DL-DVD read speed which is an average of around 12MB/s)
Something wonky is at play here and I don't have a clue what it is unless the drive was replaced with a faster one.

There's nothing wonky at play.
The dummy\padding data is before the game data obbiosly to improve read speed as it pushes the game data towards the edge improving read speed. Another reason why the Xbox 360 is better, see it even made you think it was faster than 12x due to it's optimizations.
9:47 does not suggest a 16x read rate. 16x would be around the 9min mark for that amount of data.
It does show a 12x read rate for DL media however.
There are some things people shouldn't dispute if they don't undedrstand what they are talking about and just listen to the person that does seem to make sense. Are people so....dumb? That they can take onboard someone's point as gospel truth purely because they write well?
Do you believe everything you read in a tabeloid newspaper, the sensationalistc style....It's got MikeB all over it.
Now I've said it before, I'll say it again, I've given you proof it's 12x. If you still are too pigheaded to just accept it. Then go and have a look and post a question on this forum...
