Supports comparison of old hard drive rates with current network data rates
Provides a clear numeric conversion based on established transfer rates
Browser-based, easy to use with simple input and output

Examples

1 IDE (UDMA mode 2) equals 0.264 Gigabit/second (SI def.)
4 IDE (UDMA mode 2) equals 1.056 Gigabit/second (SI def.), calculated as 4 times 0.264

Common Use Cases

Configuring or recognizing legacy BIOS or drive-controller transfer settings for ATA/33
Benchmarking older hard drives that advertise UDMA mode 2 speeds
Troubleshooting PATA device compatibility and driver issues related to transfer rates
Comparing legacy disk throughput with modern networking speeds
Planning and upgrading telecommunications or network infrastructure while referencing legacy data rates

Tips & Best Practices

Understand that IDE (UDMA mode 2) rates reflect theoretical maximum byte-transfer speeds on older hardware
Remember gigabit/second (SI def.) units are bit-based and ideal for expressing network link capacity
Use the converter to gain insight into obsolete hardware performance relative to modern standards
Consider overhead and protocol differences when interpreting results, as real-world throughput may vary

Limitations

Conversion is based on theoretical maximum speeds rather than sustained real transfer rates
IDE (UDMA mode 2) ratings are byte-based and represent legacy hardware limits
Gigabit/second units represent idealized bit-based capacities, not accounting for real network overhead
Direct numeric comparisons may not reflect actual performance due to hardware and protocol differences
