What Is This Tool?
This converter allows you to change data transfer rates from gigabit per second (SI definition) to IDE (UDMA mode 4), helping compare modern network speeds with legacy IDE disk interface rates.
How to Use This Tool?
-
Enter the value in gigabit/second (SI definition) you want to convert
-
Select IDE (UDMA mode 4) as the target unit
-
Click convert to see the equivalent transfer rate in IDE (UDMA mode 4)
Key Features
-
Converts data transfer units between gigabit/second (SI def.) and IDE (UDMA mode 4)
-
Browser-based and easy-to-use interface
-
Supports comparisons between modern networking and legacy storage technologies
Examples
-
1 Gigabit/second (SI def.) = 1.8939393939 IDE (UDMA mode 4)
-
5 Gigabit/second (SI def.) = 9.4696969695 IDE (UDMA mode 4)
Common Use Cases
-
Comparing LAN link speeds like Gigabit Ethernet to legacy IDE storage speeds
-
Benchmarking or maintaining older IDE storage hardware
-
Configuring or troubleshooting DMA modes in BIOS for older PCs
Tips & Best Practices
-
Verify the data source uses SI gigabit definitions, not binary-based units
-
Use this tool to assess compatibility when integrating older hardware
-
Keep in mind the IDE throughput caps when comparing speeds
Limitations
-
IDE (UDMA mode 4) throughput is limited to about 66.7 MB/s maximum
-
Practical performance can be affected by cable quality and hardware
-
This conversion does not reflect byte-based rates or binary gibibit units
Frequently Asked Questions
-
What does gigabit/second (SI def.) represent?
-
It is a data transfer rate equal to one billion bits per second, commonly used in networking to specify link capacity.
-
What is IDE (UDMA mode 4)?
-
It is a Parallel ATA transfer mode known as Ultra DMA/66, used in legacy PCs for data transfer between drives and hosts.
-
Why convert between these units?
-
Converting helps compare modern network speeds to older storage interface speeds for compatibility and benchmarking.
Key Terminology
-
Gigabit/second (SI def.)
-
A unit of data transfer rate equal to 1,000,000,000 bits per second, used to quantify data transmission speed over networks.
-
IDE (UDMA mode 4)
-
An ATA transfer mode named Ultra DMA/66, enabling data transfers up to roughly 66.7 megabytes per second on legacy IDE drives.
