What does IDE (DMA mode 1) represent?

IDE (DMA mode 1) is a direct memory access transfer mode for IDE/ATA devices that enables moderate-speed data transfers with minimal CPU involvement on legacy hardware.

How is a megabyte per second (SI) defined?

A megabyte per second (SI definition) equals one million bytes transferred every second, distinguishing it from binary units with different byte counts.

Why convert IDE (DMA mode 1) speeds to MB/s (SI)?

Converting helps translate legacy IDE DMA transfer speeds into a standard decimal unit, making it easier to compare old hardware performance with modern storage benchmarks.

What Is This Tool?

This converter helps translate data transfer speeds measured in IDE (DMA mode 1), a direct memory access mode for older IDE/ATA storage interfaces, into megabyte per second using the SI decimal definition. This enables understanding and comparing legacy hardware throughput in widely used data rate units.

How to Use This Tool?

Enter the numeric value in IDE (DMA mode 1) transfer mode you want to convert
Select IDE (DMA mode 1) as the source unit and megabyte/second (SI def.) as the target
Click convert to receive the equivalent data transfer rate in megabytes per second
Use the result to interpret or compare legacy IDE DMA rates in common MB/s units

Key Features

Converts from IDE (DMA mode 1) to megabyte/second with SI definition
Supports legacy data transfer rate measurements for IDE/ATA devices
Facilitates comparison between old IDE DMA speeds and modern MB/s benchmarks
Uses standardized decimal unit (1 MB/s = 10^6 bytes/s) for clarity
Useful for hardware diagnostics, performance analysis, and engineering contexts

Examples

2 IDE (DMA mode 1) equals 26.6 megabyte/second (SI def.)
0.5 IDE (DMA mode 1) equals 6.65 megabyte/second (SI def.)

Common Use Cases

Translating transfer speeds of older IDE or ATA hard drives for performance reports
Troubleshooting or configuring legacy BIOS and OS ATA driver DMA settings
Tuning and verifying compatibility of IDE devices on legacy controllers
Comparing legacy hardware throughput with modern storage device data rates
Documenting data transfer rates in engineering or technical materials

Tips & Best Practices

Ensure clear distinction between SI megabytes per second and binary-based units like MiB/s
Use this conversion primarily for legacy IDE/ATA hardware performance contexts
Understand that real transfer rates may vary due to protocol overhead or inefficiencies
Verify device and system compatibility when examining DMA mode settings
Use standardized units to maintain clarity in performance reporting

Limitations

IDE (DMA mode 1) speeds apply only to legacy IDE interface timing and protocols
Conversion does not account for transfer overhead or actual throughput variability
Differences between SI-based and binary data units may cause discrepancies if confused
Not suitable for direct comparison with modern high-speed interfaces without context
