What does IDE (UDMA-66) represent?

IDE (UDMA-66) is a Parallel ATA transfer mode defining a theoretical maximum data rate of about 66.7 MB/s for legacy PATA devices.

Why convert from IDE (UDMA-66) to MB/s?

Converting to MB/s helps users understand and compare transfer speeds in a widely recognized and standard unit.

Does the converted MB/s value reflect actual data transfer speeds?

The conversion represents the theoretical peak burst rate; actual speeds may be lower due to various hardware and system factors.

Tips & Best Practices

Use this tool to compare legacy device speeds against modern units for clearer understanding.
Remember that the rated IDE (UDMA-66) speed is theoretical and actual performance may vary.
Be aware of different megabyte definitions (decimal vs binary) which can affect precision.

Limitations

The IDE (UDMA-66) value represents a maximum burst transfer rate, not sustained speeds.
Actual transfer speeds depend on device condition, cable quality, and system factors.
Differences between decimal and binary megabyte definitions may cause slight conversion discrepancies.
