What Is This Tool?
This unit converter transforms data transfer rates measured in gigabytes per second (SI definition) into the legacy IDE (PIO mode 4) timing units used for older ATA/IDE storage devices. It helps users compare modern high-speed data throughput with classic CPU-controlled storage transfer modes.
How to Use This Tool?
-
Enter the numerical value in gigabyte/second (SI def.) you want to convert
-
Select IDE (PIO mode 4) as the target unit
-
Click the convert button to see the equivalent value in IDE (PIO mode 4)
-
Interpret the result for diagnostics, benchmarking, or compatibility checks
Key Features
-
Converts data transfer rates from gigabyte/second (SI def.) to IDE (PIO mode 4)
-
Uses the exact conversion factor between these units
-
Supports benchmarking and diagnostics for legacy storage devices
-
Browser-based and easy to use without additional software
Examples
-
2 gigabyte/second (SI def.) equals approximately 120.48 IDE (PIO mode 4)
-
0.5 gigabyte/second (SI def.) equals about 30.12 IDE (PIO mode 4)
Common Use Cases
-
Comparing modern network speeds with legacy ATA/IDE transfer modes
-
Diagnosing and configuring older PC or embedded system storage settings
-
Evaluating upgrade needs by benchmarking older drives against new devices
-
Maintaining compatibility in retro-computing or industrial systems
Tips & Best Practices
-
Use this converter primarily for legacy system compatibility assessments
-
Understand that IDE (PIO mode 4) represents timing modes, not physical storage units
-
Consider complementary tools for detailed performance analysis
-
Keep in mind the theoretical nature of conversions reflecting older transfer technologies
Limitations
-
IDE (PIO mode 4) has a limited maximum throughput near 16.7 MB/s
-
Conversions are mostly theoretical for benchmarking older devices rather than actual speed measurement
-
Transfer overhead and different technologies mean direct conversions do not capture real-world performance
-
This tool is not suitable for assessing modern storage performance directly
Frequently Asked Questions
-
What does gigabyte/second (SI def.) represent?
-
It represents a data rate with 1 gigabyte equal to 10^9 bytes transferred every second, using decimal SI prefixes.
-
What is IDE (PIO mode 4)?
-
IDE (PIO mode 4) is an older CPU-driven data transfer timing mode for ATA/IDE devices with a max theoretical throughput of about 16.7 MB/s.
-
Why would I convert between these units?
-
To compare or interpret modern data transfer rates against legacy storage performances for diagnostics, benchmarking, or compatibility.
Key Terminology
-
Gigabyte/second (SI def.)
-
A data rate denoting one gigabyte (10^9 bytes) transferred every second using SI decimal units.
-
IDE (PIO mode 4)
-
An older Programmed Input/Output transfer timing mode for ATA/IDE storage devices controlled directly by the CPU.
