IDE (DMA mode 0) to IDE (UDMA mode 4)
Please provide values below to convert IDE (DMA mode 0) to IDE (UDMA mode 4), or change ↔.
IDE (DMA mode 0)
Definition: Refers to Direct Memory Access (DMA) mode 0 for IDE devices, with data transfer rates of up to 4.2 MB/s.
Funfact: DMA mode 0 allowed the system to transfer data directly between devices and memory, reducing CPU overhead compared to PIO modes.
IDE (UDMA mode 4)
Definition: Refers to UDMA mode 4 for IDE devices, with data transfer rates of up to 66 MB/s.
Funfact: UDMA mode 4 became a standard for high-performance IDE devices, including hard drives and optical drives.

How to Convert IDE (DMA mode 0) to IDE (UDMA mode 4)
1 IDE (DMA mode 0) = 0.0636363636 IDE (UDMA mode 4)
1 IDE (UDMA mode 4) = 15.714285714 IDE (DMA mode 0)
we use cross multiplication method
IDE (DMA mode 0) → IDE (UDMA mode 4)
1 → 0.0636363636
1.5 → ?( suppose x)
=>1.5*0.0636363636=1*x
by simplifying
x=0.0954545455
