What Is This Tool?
This tool allows you to convert data transfer rates from IDE (UDMA mode 4), a legacy Parallel ATA transfer mode, to H11, a theoretical unit scale used for experimental comparison despite not being a standard data transfer unit.
How to Use This Tool?
-
Enter the value in IDE (UDMA mode 4) units you want to convert
-
Select IDE (UDMA mode 4) as the input unit
-
Choose H11 as the output unit
-
Click convert to obtain the equivalent H11 value
Key Features
-

-
Browser-based and user-friendly interface
-
Displays results based on a fixed conversion formula
Examples
-
2 IDE (UDMA mode 4) equals 687.5 H11
-
0.5 IDE (UDMA mode 4) equals 171.875 H11
Common Use Cases
-
Translating legacy IDE data transfer speeds for benchmarking
-
Comparing outdated hardware transfer modes to alternative units
-
Supporting data recovery efforts involving older IDE devices
Tips & Best Practices
-
Ensure correct unit selection to avoid misinterpretation
-
Use the converter for theoretical or experimental comparison purposes
-
Remember that H11 is not a standard or widely recognized unit
-
Cross-check with standard units like MB/s when accuracy matters
Limitations
-
H11 is not a standard or industry-recognized data transfer unit
-
IDE (UDMA mode 4) speeds are theoretical and may vary in real use
-
Converting to H11 might have limited practical application
-
Avoid mistaking H11 for conventional transfer speed units
Frequently Asked Questions
-
What is IDE (UDMA mode 4)?
-
IDE (UDMA mode 4), also known as Ultra DMA/66, is a legacy Parallel ATA transfer mode used in older computers with a maximum theoretical data rate of about 66.7 megabytes per second.
-
Is H11 a standard unit for data transfer?
-
No, H11 is not a recognized or standard unit for data transfer; standard metrics use bits, bytes, and multiples thereof.
-
Why convert IDE (UDMA mode 4) to H11?
-
Users may convert to H11 for theoretical or experimental translation of legacy IDE speeds into an alternative unit scale during benchmarking or data recovery.
Key Terminology
-
IDE (UDMA mode 4)
-
A Parallel ATA transfer mode with Ultra DMA protocol, enabling data transfer at about 66.7 megabytes per second using an 80-conductor IDE cable.
-
H11
-
A non-standard, theoretical unit for data transfer often used for experimental or comparative purposes, not recognized in conventional data measurement.
-
Data Transfer Rate
-
The speed at which data is moved from one device to another, commonly measured in bits or bytes per second.
