What is IDE (DMA mode 2)?

It is a legacy Parallel ATA data transfer mode allowing direct memory access with lower CPU usage, used in older PATA/IDE devices.

How does kilobyte/second (SI def.) differ from KiB/s?

Kilobyte per second (SI def.) uses a decimal base of 1000 bytes per kilobyte, while kibibyte per second uses a binary base of 1024 bytes.

Why convert IDE (DMA mode 2) speeds to kilobyte/second?

To express legacy device transfer rates in a modern, widely understood unit suitable for benchmarking and reporting.

Click the convert button to get the equivalent data rate in kilobyte/second.
Review the conversion result to understand the data transfer rate in SI units.

Key Features

Converts IDE (DMA mode 2) rates to kilobyte per second (SI definition).
Based on established conversion rate for legacy PATA/IDE interfaces.
Provides clear examples converting various values.
Supports benchmarking and troubleshooting older storage devices.
Browser-based and easy to use without additional software.

Examples

2 IDE (DMA mode 2) equals 33200 kilobyte/second (SI def.).
0.5 IDE (DMA mode 2) equals 8300 kilobyte/second (SI def.).
Conversion helps quantify legacy IDE device transfer speeds in modern SI units.

Common Use Cases

Configuring and diagnosing legacy PATA/IDE hard drives and optical drives.
Firmware or BIOS negotiation of data transfer modes on older systems.
Benchmarking or troubleshooting storage interfaces with legacy DMA modes.
Reporting data transfer speeds in universally recognized SI units.

Tips & Best Practices

Use this conversion to compare legacy IDE transfer rates with modern units.
Remember that kilobyte/second here uses the SI decimal standard (1000 bytes).
Take care when comparing results with binary-based units like kibibytes per second.
Account for possible variations in real transfer rates due to hardware and system factors.

Limitations

Applicable only to older PATA/IDE interfaces and their Multiword DMA mode 2.
Less relevant for modern storage standards such as SATA or NVMe.
Kilobyte/second in SI differs from binary units, which may cause confusion.
Conversion reflects theoretical maximum throughput, not actual real-world rates.
