Examples

1 IDE (PIO mode 4) = 21.0392902408 T2 (signal)
2 IDE (PIO mode 4) = 42.0785804816 T2 (signal)

Common Use Cases

Configuring or diagnosing older ATA/IDE drives and BIOS settings on legacy systems
Benchmarking or comparing performance of historic storage devices against telecom line rates
Supporting legacy industrial or retro-computing environments requiring historical timing modes
Evaluating early telecom leased lines and trunk connections in enterprise PBX systems

Tips & Best Practices

Use this tool to understand legacy system throughput comparisons rather than precise physical measurements
Apply the conversion mainly for benchmarking and interoperability assessments involving CPU-driven IDE modes and telecom trunking rates
Remember the values reflect theoretical or nominal rates since both units describe different signal and timing concepts

Limitations

IDE (PIO mode 4) denotes a timing mode, so throughput values are theoretical and dependent on CPU control
T2 (signal) is a historical telecom line rate, not a direct measure of data storage speed
Conversions are approximate and best used for contextual understanding rather than exact equivalence
Modern systems generally use faster transfer methods, making this conversion mostly relevant for legacy equipment
