What does IDE (PIO mode 2) measure?

IDE (PIO mode 2) defines the timing and maximum effective data transfer rates for CPU-driven programmed I/O cycles between a host and storage device in older IDE systems.

What is an OC24 data rate?

OC24 denotes the capacity of an optical fiber channel in SONET networks, equal to 24 times the base OC-1 rate, approximately 1.24416 Gbit/s.

Why convert from IDE (PIO mode 2) to OC24?

Converting helps compare legacy PIO transfer speeds with modern high-capacity optical network bandwidths for network planning, diagnostics, and performance analysis.
