What does IDE (UDMA mode 2) represent in data transfer?

It is a specific Ultra DMA transfer mode for Parallel ATA interfaces, often called ATA/33, with a maximum theoretical rate near 33.3 megabytes per second.

How is a megabyte per second (SI def.) defined?

It is a data transfer rate equal to one million bytes (10^6 bytes) transferred each second, different from the binary mebibyte per second unit.

Why convert IDE (UDMA mode 2) rates to megabytes per second?

To translate legacy transfer speeds into standard SI units for easier comparison with modern device performance and technical specs.

Troubleshooting PATA system compatibility and driver issues involving transfer speeds.
Comparing legacy transfer rates to modern storage device speeds in standard units.

Tips & Best Practices

Use this tool for converting theoretical maximum IDE (UDMA mode 2) rates rather than actual measured speeds.
Consider the difference between decimal megabyte/second and binary mebibyte/second units when interpreting results.
Apply conversions primarily for legacy hardware contexts like diagnostics and benchmarking.

Limitations

Conversion shows theoretical max transfer rates without accounting for overhead or hardware constraints.
IDE (UDMA mode 2) speeds apply only to legacy PATA systems and may not be directly comparable to newer interface rates.
Does not reflect actual data throughput which can vary due to signal quality and other factors.
