What is IDE (PIO mode 1)?

IDE (PIO mode 1) is a Programmed Input/Output transfer mode used in legacy PATA devices where the CPU controls each data transfer cycle, resulting in moderate throughput and higher CPU overhead.

What does OC12 represent in data transfer?

OC12 is a SONET optical carrier rate carrying 12 STS-1 channels with a nominal rate of 622.08 megabits per second, widely used in high-capacity fiber-optic telecommunications networks.

Why convert from IDE (PIO mode 1) to OC12?

Converting helps relate legacy storage device transfer speeds to modern high-capacity optical network rates, useful for benchmarking and performance comparisons.
