    Default What determines the ultra DMA mode level settings?

    Is the ultra DMA mode level settings determined by the optical drive itself or is the size of the CPU (resources) a factor to determine the ultra DMA mode setting level.

    Current setup:
    AMD Athlon XP 3200+
    2191 MHZ
    1.0 gb ram
    All IDE cables are 40 pin, 80 leads

    IDE connections:
    primary IDE master Plextor 760A (ultra DMA mode 4)
    primary IDE slave Vacant

    secondary IDE master Plextor 708A (ultra DMA mode 2)
    secondary IDE slave Vacant

    SATA connections;
    primary 120 gb hard drive
    secondary Plextor 716SA (ultra DMA mode 6)

    dma was developed to relieve cpu use during transfers, it's handled by the
    ide controller chipset so cpu speed does not impact dma significantly.
    DMA 2 at 33MB/s exceeds any sustained transfer from any optical drive.
    At 33MB/s we are talking 24X burn or read speeds, kind of hard to get the disks spinning that much faster, on that sata drive I wouldn't even want to be in the same room with it trying to spin 5 times faster.
    Now burst over interface is another story, the dma 4(100MB/s) will give you an extra 66+MB/s, but the cache on the drive will only hold 1/30 of a second's transfer.

    smoke and mirrors but sounds nice
