What Is This Tool?
This converter enables you to translate data transfer values between IDE (DMA mode 2) and IDE (DMA mode 0), both legacy PATA/IDE direct memory access modes used in older computer storage devices.
How to Use This Tool?
-
Enter the value in IDE (DMA mode 2) units you want to convert
-
Select IDE (DMA mode 0) as the target unit
-
Click the convert button to see the equivalent value
-
Use the results to analyze or configure legacy IDE device transfer settings
Key Features
-
Converts data transfer from IDE (DMA mode 2) to IDE (DMA mode 0)
-
Supports legacy PATA/IDE storage device modes
-
Browser-based and easy to use
-
Helps compare transfer throughput and CPU usage between modes
Examples
-
2 IDE (DMA mode 2) equals 7.9047619048 IDE (DMA mode 0)
-
0.5 IDE (DMA mode 2) equals 1.9761904762 IDE (DMA mode 0)
Common Use Cases
-
Comparing transfer speeds between faster and slower IDE DMA modes
-
Diagnosing or configuring legacy PATA/IDE hard drives and optical drives
-
Firmware or BIOS development involving IDE device DMA mode negotiation
-
Optimizing throughput and CPU load on older storage interfaces
Tips & Best Practices
-
Use this conversion to better understand legacy device performance
-
Apply conversions during troubleshooting or firmware updates
-
Recognize that both modes are for legacy PATA interfaces only
-
Consider device condition and system factors when analyzing results
Limitations
-
Both modes are for outdated PATA/IDE standards, not modern SATA or NVMe devices
-
Actual data transfer rates may differ due to hardware specifics and cable quality
-
Conversion shows relative mode capability, not absolute data size or timing
Frequently Asked Questions
-
What does IDE (DMA mode 2) mean?
-
IDE (DMA mode 2) is a Multiword DMA transfer mode for legacy PATA/IDE devices that allows data to move directly to or from system memory with reduced CPU involvement.
-
Why convert from IDE (DMA mode 2) to IDE (DMA mode 0)?
-
Converting helps compare or translate transfer rates between different IDE DMA modes, useful for system optimization, troubleshooting, or device configuration.
-
Can this conversion be used for modern SATA drives?
-
No, this conversion applies only to legacy PATA/IDE standards and does not reflect modern SATA or NVMe device transfers.
Key Terminology
-
IDE (DMA mode 2)
-
A Multiword DMA mode 2 transfer mode in legacy PATA/IDE devices that enables direct memory data transfer with low CPU overhead.
-
IDE (DMA mode 0)
-
The first and lowest direct memory access transfer mode specified for ATA/IDE devices as per ATA multiword DMA standards.
-
PATA
-
Parallel ATA, a legacy interface standard for connecting storage devices to a computer.
