Click the convert button to see the equivalent OC3 rate.

Key Features

Converts between IDE (UDMA mode 0) and OC3 data transfer rates.
Facilitates comparison of legacy PATA/IDE speeds with fiber-optic telecommunication rates.
Browser-based and easy to use for quick network capacity assessments.

Examples

1 IDE (UDMA mode 0) equals approximately 0.853909465 OC3.
10 IDE (UDMA mode 0) equals approximately 8.53909465 OC3.

Common Use Cases

Specifying or diagnosing throughput for legacy PATA/IDE hard drives and CD/DVD drives.
Troubleshooting or selecting DMA timing settings in BIOS or device drivers.
Comparing legacy interface limits during migrations from PATA to faster interfaces like SATA or USB.
Planning telecommunications backbone links and ISP infrastructure involving OC3 lines.
