What Is This Tool?
This converter allows you to translate data transfer speeds measured in megabytes per second (SI definition) into IDE (PIO mode 2) units, enabling comparisons between modern transfer rates and legacy ATA/IDE timing specifications.
How to Use This Tool?
-
Input the value in megabyte/second (SI definition).
-
Select megabyte/second (SI def.) as the source unit.
-
Choose IDE (PIO mode 2) as the target unit.
-
Click convert to get the equivalent value in IDE (PIO mode 2).
Key Features
-
Converts data transfer rates from megabyte/second (SI definition) to IDE (PIO mode 2).
-
Supports analysis of legacy ATA/IDE drive timing through programmed I/O modes.
-
Facilitates diagnostics and configuration for vintage PC storage devices.
Examples
-
10 megabyte/second (SI def.) equals approximately 1.204819277 IDE (PIO mode 2).
-
100 megabyte/second (SI def.) converts to about 12.04819277 IDE (PIO mode 2).
Common Use Cases
-
Reporting and comparing modern data transfer speeds with legacy IDE drive performance.
-
Configuring BIOS or firmware settings for older ATA/IDE drives.
-
Diagnosing performance issues when operating systems revert from DMA to PIO mode.
Tips & Best Practices
-
Use this converter primarily for legacy system diagnostics and hardware analysis.
-
Confirm the unit definitions before converting to ensure correct interpretation.
-
Refer to device driver reports to understand the PIO mode negotiated by IDE devices.
Limitations
-
IDE (PIO mode 2) measures timing specifications rather than standard throughput.
-
Conversion applies chiefly to legacy hardware and is not suitable for modern throughput evaluation.
-
Modern storage technologies usually rely on DMA modes or newer interfaces, making PIO obsolete.
Frequently Asked Questions
-
Why convert megabyte/second to IDE (PIO mode 2)?
-
Converting helps compare modern data rates with legacy ATA/IDE timing for diagnostics and configuration of older hardware.
-
Is IDE (PIO mode 2) still used in modern systems?
-
No, it is a legacy transfer mode relevant mostly for older IDE drives and vintage PC maintenance.
-
What does 1 megabyte per second (SI def.) represent?
-
It represents a transfer rate of one million bytes per second, using decimal units (10^6 bytes/s).
Key Terminology
-
Megabyte/second (SI definition)
-
A data transfer rate equal to 1,000,000 bytes transferred each second, based on decimal units.
-
IDE (PIO mode 2)
-
A legacy transfer mode defining CPU-driven programmed I/O timing for ATA/IDE devices.
-
Programmed Input/Output (PIO)
-
A method of data transfer where the CPU actively controls each data cycle without DMA assistance.
