What is IDE (DMA mode 0)?

IDE (DMA mode 0) is the earliest and slowest direct memory access transfer mode for ATA/IDE devices, allowing data blocks to be moved into system memory without CPU intervention.

What does gigabyte per second (SI def.) represent?

It is a data transfer rate equal to one billion bytes transferred each second, based on SI decimal units rather than binary multiples.

Why convert IDE (DMA mode 0) speeds to gigabyte/second?

This conversion helps compare legacy device transfer rates with contemporary storage and networking throughput figures for benchmarking and system upgrades.

Click convert to see the equivalent transfer rate in gigabyte/second
Use the provided formula and examples for manual calculations if needed

Key Features

Converts IDE (DMA mode 0) transfer speeds into gigabytes per second using SI units
Supports comparison between legacy PATA device speeds and modern data throughput
Browser-based and easy-to-use interface for quick conversions
Provides clear examples to demonstrate the calculation
Useful for hardware engineers, system maintainers, and embedded developers

Examples

5 IDE (DMA mode 0) = 5 × 0.0042 = 0.021 gigabyte/second (SI def.)
10 IDE (DMA mode 0) = 10 × 0.0042 = 0.042 gigabyte/second (SI def.)

Common Use Cases

Benchmarking legacy PATA hard drive transfer rates against modern storage devices
Translating outdated DMA mode data speeds to standardized SI-based units
Assisting embedded system developers reducing CPU overhead using legacy IDE interfaces
IT infrastructure planning where data transfer rates from both old and new technologies are analyzed
OS and BIOS driver development that configures or detects IDE DMA modes during startup

Tips & Best Practices

Always verify you are converting from IDE (DMA mode 0) specifically to avoid errors
Use the conversion factor 0.0042 as the multiplier for accurate results
Consider unit context, especially when comparing to binary-based data rates
Keep in mind the legacy nature of IDE (DMA mode 0) and its low throughput
Apply conversions to assist in system upgrades and compatibility assessments

Limitations

Conversions yield small values due to the low-speed nature of IDE (DMA mode 0)
Gigabyte per second values use SI decimal prefixes, unlike binary-based units commonly used in computing
Results may not directly equate to performance in binary-prefixed units such as gibibytes per second
Not suitable for representing modern high-speed data transfer modes directly
Accuracy differences exist compared to newer transfer rate units, limiting precision in some use cases
