What Is This Tool?
This unit converter translates data transfer speeds between IDE (UDMA mode 0), a Parallel ATA interface mode, and FireWire (IEEE-1394), a high-speed serial bus standard. It helps compare legacy PATA device speeds with modern serial bus interfaces commonly used in multimedia and external storage.
How to Use This Tool?
-
Enter the value in IDE (UDMA mode 0) units you want to convert
-
Select FireWire (IEEE-1394) as the target unit
-
Click convert to get the equivalent data transfer rate
-
Use the result to compare device performance or interface limits
Key Features
-
Converts data transfer rates from IDE (UDMA mode 0) to FireWire (IEEE-1394)
-
Supports conversion using a defined rate based on standard interface rates
-
Browser-based and user-friendly interface
-
Allows easy comparison of legacy and modern data transfer technologies
Examples
-
1 IDE (UDMA mode 0) converts to approximately 0.332 FireWire (IEEE-1394)
-
5 IDE (UDMA mode 0) converts to approximately 1.66 FireWire (IEEE-1394)
Common Use Cases
-
Comparing throughput of legacy PATA/IDE drives and CD/DVD drives
-
Diagnosing and selecting DMA timing for device drivers or BIOS
-
Migrating systems from PATA interfaces to faster connections like FireWire
-
Connecting external audio, video, and storage devices using FireWire
Tips & Best Practices
-
Verify device specifications when interpreting converted values
-
Consider interface protocol differences impacting actual throughput
-
Use this tool to aid in multimedia production and data backup planning
-
Remember that physical cable and system setup influence speeds
Limitations
-
Conversion is approximate due to different data transfer methods (parallel vs serial)
-
Actual transfer rates depend on device implementation and system configuration
-
Overheads and protocol differences can affect effective throughput
Frequently Asked Questions
-
What does IDE (UDMA mode 0) represent?
-
IDE (UDMA mode 0) is an Ultra DMA transfer mode for PATA/IDE devices specifying timing and nominal maximum raw data transfer rates.
-
What is FireWire (IEEE-1394) commonly used for?
-
FireWire is used for high-speed data transfers including video capture, external drives, and professional audio streaming.
-
Is the conversion between IDE and FireWire exact?
-
No, the conversion is approximate because IDE uses parallel transfers while FireWire uses serial communication, affecting throughput.
Key Terminology
-
IDE (UDMA mode 0)
-
An Ultra DMA transfer mode for Parallel ATA devices defining timing and nominal maximum data rates for DMA transfers.
-
FireWire (IEEE 1394)
-
An IEEE-standard serial bus interface for high-speed data transfers designed for isochronous and asynchronous streams.
-
Data Transfer Rate
-
The speed at which data is transmitted between devices, measured in units such as megabytes per second or equivalent unit conversions.
