data rates

i want to know how many mb/s a 5x DVD drive can transfer.

spin rate at 5.0x = XXmb/s

The amount of time taken to write a disc depends upon the writing speed of the recorder, the writing mode used by the recorder, the amount of information to be written and if verification or defect management is employed. At single speed (1x) a recorder writes 1.32 MB (1,385,000 bytes) of data per second and a multiple of that figure at each speed increment above 1x. So a 5x recorder will have a transfer rate of 6,925,000 bytes/sec (6.60 Mb/sec).

how fast is Multi-Word DMA Mode 2?

nvm, i found the answer for that already. 16.6MB/s

what DMA mode should my DVD drive be in? i think Multi-Word DMA Mode 2 is a bit low for a 5x DVD drive and Ultra DMA Mode 2 is a bit high for a 10x4x32 CD burner.
