What does IDE (UDMA mode 4) represent?

IDE (UDMA mode 4) is a Parallel ATA transfer mode using Ultra DMA protocol for data transfer between a drive and host, reaching theoretical speeds of about 66.7 megabytes per second.

What is the T4 (signal) used for?

T4 (signal) is a high-order trunk signal in the North American T-carrier hierarchy used primarily in long-distance backbone telephone links, carrying multiplexed channels at around 274.176 megabits per second.

Can I directly interchange IDE (UDMA mode 4) and T4 (signal) units in hardware?

No, these units represent different signal and interface standards and are mostly used for comparative or historical analysis rather than direct hardware interchangeability.

Key Features

Accurate rate conversion between IDE (UDMA mode 4) and T4 (signal).
Provides examples for clarity on conversion usage.
Suitable for benchmarking and legacy system analysis.
Supports understanding of legacy PC storage and telecom backbone rates.

Examples

2 IDE (UDMA mode 4) equals approximately 3.8515406162 T4 (signal).
0.5 IDE (UDMA mode 4) equals approximately 0.96288515405 T4 (signal).

Common Use Cases

Connecting PATA/IDE hard drives in legacy PC systems from the late 1990s and early 2000s.
Testing and validating legacy telecommunications multiplexers using T4 signals.
Benchmarking and maintaining older storage hardware and telecom infrastructure.
Converting data rates for analysis in computer hardware maintenance and legacy network management.

Tips & Best Practices

Always double-check unit selections before conversion.
Use this tool primarily for comparative or historical analysis.
Account for differences in units: IDE rates are in megabytes per second, T4 rates in megabits per second multiplexed signals.
Consider the limitations when using conversions for practical data transfer estimations.

Limitations

Conversion reflects theoretical maximum throughput, not real-world sustained speeds.
Units represent different standards, so conversions are not meant for direct interchangeability.
T4 (signal) measures multiplexed megabits per second, while IDE (UDMA mode 4) rates are in megabytes per second.
Primarily useful for comparative or legacy system analysis rather than operational conversions.
