Um. Sounds like a red herring to me. The drive only supports 33 MB/s.

The manual, which can be found at
(phew) says (page 10):

Data transfer rate
*Sustained          CD-ROM : 6000 Kbytes/s (40X max)
                    DVD-ROM : 22160 Kbytes/s (16X max)
*Burst(ATAPI)       16.6 Mbytes/s (PIO Mode 4), (MULTI-DMA Mode 2)
                    33.3 Mbytes/s (Ultra-DMA Mode 2)

So 33 MB/s is all you're going to get out of the drive interface. And
this is enough for 16x DVD.

Hope this helps,
