IDE (PIO mode 4) to IDE (UDMA mode 2)
Please provide values below to convert IDE (PIO mode 4) to IDE (UDMA mode 2), or change ↔.
IDE (PIO mode 4)
Definition: Refers to PIO mode 4 for IDE devices, with data transfer rates of up to 16.6 MB/s.
Funfact: PIO mode 4 was often used in older systems but was gradually replaced by more efficient transfer modes, such as DMA and UDMA.
IDE (UDMA mode 2)
Definition: Refers to UDMA mode 2 for IDE devices, with data transfer rates of up to 33 MB/s.
Funfact: UDMA mode 2 increased data transfer rates, and it was used in hard drives and optical drives for better performance during the early 2000s.

How to Convert IDE (PIO mode 4) to IDE (UDMA mode 2)
1 IDE (PIO mode 4) = 0.503030303 IDE (UDMA mode 2)
1 IDE (UDMA mode 2) = 1.9879518072 IDE (PIO mode 4)
we use cross multiplication method
IDE (PIO mode 4) → IDE (UDMA mode 2)
1 → 0.503030303
1.5 → ?( suppose x)
=>1.5*0.503030303=1*x
by simplifying
x=0.7545454545
