Negative press from a MS shill, not surprising.
From a slashdotter who knows a quite a bit about blu-ray drives:
You can see Ozymandias neglecting facts about 12 speed DVD drives in general. 16MB/second is a maximum throughput on a small part of the outer ring. That throughput you can get only on single layer discs as well. Most 360 games are dual layer, so max speed is 8x, again for a very small portion of the disc.A 12x CAV drive like the one in the 360 will be 12x speed for around 15% of the outer disc, that figure is peak performance. The closer to the inner ring it gets the slower accesses get (5x speed on the inner ring) - probable average: around 8x speed. Another interesting thing seems to escape everyone is that the 12x DVD drive in the 360 only reads dual layer discs at a maximum of 8x speed. As it was in single layer, the 8x speed is peak performance. The 2x speed BD drive performs quite well in this case: a BD25 on PS3 fares better than a DVD9 on the 360. The great majority of 360 games are and will be pressed on DVD9s. Another interesting point with existing CLV BD drives is that they do not have the dual layer penalization with DVD dics. If a BD drive is rated to read DVDs at 8x, it will read dual layer DVDs at 8x as well. This is why Sony is comfortable with its choice and knows it will hold its own against MS's choice in the DVD format.
