IDE (PIO mode 4) to IDE (UDMA mode 1)
Please provide values below to convert IDE (PIO mode 4) to IDE (UDMA mode 1), 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 1)
Definition: Refers to UDMA mode 1 for IDE devices, with data transfer rates of up to 25 MB/s.
Funfact: UDMA mode 1 became widely adopted in the late 90s and early 2000s, offering faster transfer rates than earlier PIO and DMA modes.

How to Convert IDE (PIO mode 4) to IDE (UDMA mode 1)
1 IDE (PIO mode 4) = 0.664 IDE (UDMA mode 1)
1 IDE (UDMA mode 1) = 1.5060240964 IDE (PIO mode 4)
we use cross multiplication method
IDE (PIO mode 4) → IDE (UDMA mode 1)
1 → 0.664
1.5 → ?( suppose x)
=>1.5*0.664=1*x
by simplifying
x=0.996
