View the converted data transfer rate in OC3 based on the predefined formula.

Key Features

Converts data transfer rates from IDE (PIO mode 3) to OC3 units.
Supports comparison between legacy CPU-driven storage throughput and modern optical network speeds.
Provides theoretical conversion based on standard maximum throughput values.
Useful for telecommunications and networking infrastructure analysis.

Examples

5 IDE (PIO mode 3) equals 2.8549382715 OC3 using the conversion formula.
10 IDE (PIO mode 3) equals 5.709876543 OC3 following the same conversion rule.

Common Use Cases

Integrating data transfer rates for devices in retrocomputing and embedded system environments.
Benchmarking performance between CPU-driven IDE modes and high-speed optical carrier links.

Tips & Best Practices

Ensure you input data rates in the correct unit (IDE PIO mode 3) before conversion.
Remember that IDE throughput is raw and CPU-driven, different from OC3's consistent optical rate.
Use the results as theoretical estimates rather than exact real-world speeds.

Limitations

IDE (PIO mode 3) rates do not include effects of DMA and may reflect lower actual speeds.
The conversion assumes theoretical maximum rates without accounting for network overhead or latency.
IDE values are in megabytes per second while OC3 is measured in megabits per second, requiring careful consideration.
