What does IDE (UDMA mode 3) represent?

It is an Ultra DMA transfer mode for Parallel ATA interfaces providing a theoretical max raw transfer rate around 44.4 MB/s for legacy PATA/IDE devices.

What is STS3c (payload) used for?

STS3c payload is a SONET transport container carrying high-bandwidth client signals at about 155.52 Mbps for optical network communications.

Why convert between these two units?

Conversion helps compare throughput between older PATA/IDE storage device speeds and modern SONET optical transport rates for system integration and network planning.

Tips & Best Practices

Remember that IDE (UDMA mode 3) rates reflect theoretical maxima which may vary in practice
Consider SONET framing and overhead which slightly reduce the net user payload of STS3c
Use the conversion primarily for high-level comparisons rather than for hardware substitution
Verify configurations in both storage and network equipment to ensure compatibility

Limitations

IDE (UDMA mode 3) represents a legacy storage interface with theoretical maximum rates
STS3c payload excludes SONET overhead, so actual user data rates are slightly lower
These units correspond to different technology domains making direct hardware correlation limited
Conversion is best suited for conceptual throughput comparison rather than exact hardware matching
