What does OC24 represent?

OC24 is a SONET rate designation indicating 24 times the base OC-1 rate, equaling 1,244.16 Mbit/s.

Why is IDE (PIO mode 0) so much slower than OC24?

IDE (PIO mode 0) uses CPU-driven data transfers without DMA, resulting in low maximum throughput suited for legacy hardware.

Can I use this conversion for real-time data transfer planning?

No, this conversion is theoretical and meant for comparison or historical reference, not for live data transfer designs.
