What is IDE (DMA mode 0)?

IDE (DMA mode 0) is the first and lowest-speed direct memory access mode defined for ATA/IDE devices, enabling data blocks to move into system memory without CPU-driven programmed I/O.

What does terabyte per second (SI def.) measure?

A terabyte per second (SI definition) measures data transfer rates as one trillion bytes moved each second, commonly used in high-performance computing and data center environments.

Why convert from IDE (DMA mode 0) to terabyte/second (SI def.)?

Converting helps express legacy device speeds in standard modern units, facilitating comparisons between older hardware transfer capabilities and current data rates.

What Is This Tool?

This unit converter allows you to translate data transfer rates measured in IDE (DMA mode 0), an early and slower direct memory access mode for ATA/IDE devices, into terabyte per second (SI def.), a modern unit expressing very high data throughput.

How to Use This Tool?

Input the value in IDE (DMA mode 0) units you wish to convert
Select terabyte/second (SI def.) as the target unit
Execute the conversion to see the corresponding data rate in terabytes per second

Key Features

Converts legacy IDE (DMA mode 0) transfer speeds into contemporary terabyte/second units
Supports comparison between older hardware and current high-performance data rates
Provides quick access to conversion with simple interface steps

Examples

10 IDE (DMA mode 0) equals 0.000042 terabyte/second (SI def.)
100 IDE (DMA mode 0) converts to 0.00042 terabyte/second (SI def.)

Common Use Cases

Assessing legacy PATA hard drive transfer rates during system updates
Benchmarking embedded systems that still rely on IDE interfaces
Translating older hardware data rates into standardized modern units for performance comparison

Tips & Best Practices

Use this converter to understand how older DMA modes relate to current data transfer standards
Compare converted values when evaluating system upgrades or hardware replacements
Remember the limited applicability of IDE (DMA mode 0) for modern high-speed systems

Limitations

IDE (DMA mode 0) speeds are very slow and result in extremely small terabyte/second values
This transfer mode applies only to legacy PATA devices, not to newer storage technologies
Converted results offer limited relevance for high-performance computing benchmarks
