The higher the MODE value is, the best is the hard disk data transfer rate.
But this does not mean that you can select the highest mode value as you like.
You must be sure that your hard disk supports that type of fast data transfer,
otherwise your hard disk will not be able to operate correctly.
Here are some examples of data transfer rates for IDE HDD with DMA
mode:
DMA Mode 0 The fastest data transfer rate reaches 4.16Mbyte/sec
DMA Mode 1 The fastest data transfer rate reaches 13.3Mbyte/sec
DMA Mode 2 The fastest data transfer rate reaches 16.6Mbyte/sec
Usually, PIO mode means that the hard disk data are accessed by the
CPU through the chipset and placed into memory, and the chipset is using PIO
mode to access hard disk data.
MASTER mode means that hard disk data are accessed by the chipset,
and that the chipset places the data into memory. The chipset is using DMA or
PIO mode to access data stored in the hard disk drive. The Master mode can
reduce the CPU load, especially in a Multi-task environment. This can help
system performance.
