What Is This Tool?
This converter translates data transfer speeds from IDE (UDMA mode 4), a legacy Parallel ATA transfer mode, to gigabytes per second (GB/s), a contemporary unit for measuring data rate throughput. It is useful for benchmarking and understanding older storage performance in modern terms.
How to Use This Tool?
-
Enter the data transfer value in IDE (UDMA mode 4) units
-
Select IDE (UDMA mode 4) as the input unit and gigabyte per second (GB/s) as the output unit
-
Click convert to see the equivalent data transfer rate in GB/s
Key Features
-
Converts IDE (UDMA mode 4) transfer rates to gigabytes per second (GB/s)
-
Supports data transfer analysis for legacy IDE/ATA drives
-
Facilitates comparison of old and new data transfer standards
-
Browser-based and easy to use without installation
Examples
-
1 IDE (UDMA mode 4) equals 0.0614672899 GB/s
-
10 IDE (UDMA mode 4) equals 0.614672899 GB/s
Common Use Cases
-
Benchmarking legacy PATA/IDE hardware against modern data rates
-
Configuring or troubleshooting DMA modes in older systems
-
Performing data recovery from older IDE devices by understanding transfer speeds
-
Comparing storage device throughput using a standardized unit like GB/s
Tips & Best Practices
-
Clarify whether decimal (GB) or binary (GiB) gigabyte conventions are used when reviewing transfer rates
-
Consider that actual sustained transfer speeds may vary due to hardware and protocol overhead
-
Use this tool for rough equivalence rather than precise measurements in performance-critical environments
Limitations
-
Conversion assumes a theoretical maximum throughput for IDE (UDMA mode 4) which might not reflect real-world performance
-
Differences between decimal gigabytes and binary gigabytes can cause slight discrepancies in results
Frequently Asked Questions
-
What is IDE (UDMA mode 4)?
-
IDE (UDMA mode 4), also known as Ultra DMA/66 (ATA-4), is a Parallel ATA transfer mode for IDE/ATA drives with a maximum theoretical throughput of about 66.7 megabytes per second.
-
What does gigabyte per second (GB/s) measure?
-
Gigabyte per second (GB/s) measures the amount of data transferred every second, where 1 GB often equals 1 billion bytes in decimal notation.
-
Why convert IDE (UDMA mode 4) to GB/s?
-
Converting IDE (UDMA mode 4) to GB/s helps compare legacy device speeds with modern data transfer rates, assisting in benchmarking and upgrade planning.
Key Terminology
-
IDE (UDMA mode 4)
-
A Parallel ATA transfer mode known as Ultra DMA/66, transferring data up to about 66.7 megabytes per second using an 80-conductor cable.
-
Gigabyte per second (GB/s)
-
A unit representing the transfer of one gigabyte of data per second, often interpreted as one billion bytes per second in decimal form.
