What is IDE (PIO mode 1)?

IDE (PIO mode 1) is a Programmed Input/Output transfer mode where the CPU controls each data transfer for legacy PATA devices, providing moderate throughput with higher CPU usage.

What does STS3c (signal) represent?

STS3c (signal) is a SONET electrical transport signal that combines three STS-1 channels into a single payload, offering a gross data rate of 155.52 Mbit/s for high-bandwidth telecom streams.

Why convert IDE (PIO mode 1) to STS3c (signal)?

Converting these units helps compare or translate data rates from older PATA storage technologies to modern SONET telecom signals for network provisioning, performance analysis, or legacy diagnostics.

Key Features

Online conversion between IDE (PIO mode 1) and STS3c (signal)
Based on standardized data transfer definitions from legacy and telecom technologies
Provides quick and easy translation of throughput values between distinct data transfer units

Examples

1 IDE (PIO mode 1) equals approximately 0.2674897119 STS3c (signal)
10 IDE (PIO mode 1) is equivalent to about 2.674897119 STS3c (signal)

Common Use Cases

Configuring or diagnosing legacy PATA hard drives with CPU-controlled transfer modes
Provisioning 155.52 Mbps backbone circuits or leased lines in telecom networks
Benchmarking and translating data rates for embedded or vintage systems and telecom equipment
Developing or debugging firmware and drivers requiring PIO transfer mode data rates

Tips & Best Practices

Ensure the data rate entered corresponds to IDE (PIO mode 1) values for accurate conversion
Use this tool primarily for comparison or analysis rather than direct protocol interoperability
Consider the context of transfer modes, as CPU-driven PIO has higher overhead compared to SONET signals
Use the converter to aid telecommunications provisioning or legacy system diagnostics

Limitations

The conversion assumes a linear relationship and does not factor in protocol overhead or efficiency differences
IDE (PIO mode 1) is a legacy transfer mode with significantly lower throughput than modern signals
Direct interoperability between these units is limited due to differing technology generations and control methods
