Please provide values below to convert IDE (DMA mode 0) to USB, 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.
USB
Definition: Universal Serial Bus (USB) is a standard for connecting computers and other devices, enabling data transfer and power supply between them.
Funfact: USB has evolved over the years, from USB 1.0 with speeds of 12 Mbps to USB 3.2, offering speeds up to 20 Gbps in its latest versions.

How to Convert IDE (DMA mode 0) to USB
1 IDE (DMA mode 0) = 2.8 USB
1 USB = 0.3571428571 IDE (DMA mode 0)
we use cross multiplication method
IDE (DMA mode 0) → USB
1 → 2.8
1.5 → ?( suppose x)
=>1.5*2.8=1*x
by simplifying
x=4.2
