What does IDE (UDMA mode 4) refer to?

IDE (UDMA mode 4) is a Parallel ATA transfer mode that moves data at a theoretical maximum of about 66.7 megabytes per second, commonly used in late-1990s to early-2000s PCs.

What is STS3c (payload) used for?

STS3c (payload) is a SONET transport signal providing a contiguous channel with a line rate of approximately 155.52 Mbps, used for high-bandwidth network links like OC-3 backbone circuits.

Can this converter account for actual data throughput in real-world devices?

No, the tool converts theoretical maximum rates and does not factor in overhead, framing inefficiencies, or hardware limitations affecting actual throughput.

Limitations

This conversion reflects theoretical maximum data transfer speeds and does not account for protocol overhead or real-world inefficiencies
IDE (UDMA mode 4) speeds depend on specific hardware and cabling requirements that impact actual throughput
STS3c (payload) values exclude SONET framing overhead, so usable payload is slightly less than the gross rate shown
