Seektimes are faster on CAV.
For a 3rd party source, read the earlier link. I will highlight the relevant part.
"From my own personal experience testing a Sony BD-RE drive (actually uses a Panasonic drive mechanism) and a Hitachi-LG drive of similar specs, for similar sized data sets the BD drive typically has almost the same if not significantly faster random seek times. That's generally because data sets between 4-8GB span the entire disc for for DVD-ROM while only covering a third of a BD-ROM, so on average a BD-ROM is going to have seek times in the range 50-100ms with a worst case scenario of around 200-230ms. The DVD-ROM drive will average between 110-150ms with a worst case scenario of around 170-230ms.
Of course once you start getting into larger data sets that that Blu-Ray can handle the average and worst case scenarios (which is an entire disc sweep which takes around 350-400ms) will eclipse the worst case conditions on a DVD-ROM. That being said, even with 23+GB of data with a 100 randomly generate seek sectors I still get around 100ms on average. Besides, if you find the need to randomly jump around to random sectors greater than 4GB in span, then your title has bigger issues than the capabilities of the drive."
The PS3 Blu-Ray drive only performs significantly worse with regard to seektimes in worst case scenarios as there is more data on disc (which would however imply bad design from the developer).
However it's worth noting that when the PS3 uses higher quality assets, like high quality 7.1 streamed audio and better quality textures, this covers more space on the Blu-Ray disc, this thus both impacting load- and seektimes.
