What does IDE (UDMA-66) mean?

IDE (UDMA-66), also known as Ultra DMA Mode 4 or ATA-66, is a parallel ATA transfer mode with a maximum theoretical raw data rate of 66.7 megabytes per second, used for legacy PATA storage devices.

What is OC768 used for?

OC768 is an optical carrier rate in the SONET hierarchy with a line speed around 39.8 Gbit/s, used for high-capacity fiber-optic backbone links and telecom core transport.

How does this conversion help in practice?

It helps compare legacy storage device speeds with modern optical carrier speeds, assisting in network planning, legacy system benchmarking, and integrating older hardware data rates into contemporary communications.

Examples

Converting 10 IDE (UDMA-66) results in 0.132619599 OC768.
Converting 50 IDE (UDMA-66) results in 0.663097995 OC768.

Common Use Cases

Comparing throughput of older IDE hard drives with modern high-speed optical backbone networks.
Planning network infrastructure upgrades involving data center or telecom backbone integration.
Benchmarking and analyzing data transfer capabilities in legacy and modern systems.
Supporting engineers working on legacy storage system enhancements and network backbone compatibility.

Tips & Best Practices

Use this conversion to get a general sense of performance scale rather than exact sustained rates.
Keep in mind overhead and protocol differences may affect real-world throughput compared to theoretical rates.
Consider both units' context — bytes per second for IDE and bits per second for OC768 — when interpreting results.
Apply conversions primarily for network planning and comparative analysis involving legacy and contemporary technologies.

Limitations

IDE (UDMA-66) rates represent maximum theoretical raw data rates, not guaranteed sustained speeds.
OC768 rates measure optical line speeds in bits per second, whereas IDE rates are bytes per second; this tool assumes direct comparison without protocol overhead.
Real data transfer rates can vary due to error correction, device limitations, and environmental conditions, so results are approximate.
