What is IDE (PIO mode 3)?

IDE (PIO mode 3) is a CPU-driven programmed I/O transfer mode for Parallel ATA/IDE storage devices, defined by ATA standards and used in legacy systems.

What does STS3c (signal) represent?

STS3c (signal) is a SONET electrical transport signal that concatenates three STS-1 channels, carrying high-bandwidth traffic with a gross rate of 155.52 Mbit/s.

Why convert between IDE (PIO mode 3) and STS3c (signal)?

Users convert to compare throughput between legacy CPU-driven storage modes and modern telecom SONET signals, enabling interoperability and system integration.

Is this conversion exact for practical use?

No, this conversion is theoretical and does not include overhead or encoding effects present in real-world data transfer.
