What does IDE (PIO mode 2) represent?

IDE (PIO mode 2) is an older CPU-driven data transfer timing mode used on legacy ATA/IDE devices, defining how data is moved without using DMA.

What is a megabyte per second (SI def.)?

A megabyte per second (SI def.) is a data transfer rate of 1,000,000 bytes per second, used to quantify throughput in decimal units.

Why convert IDE (PIO mode 2) values to MB/s?

Converting these values helps understand and compare vintage IDE drive speeds using modern, widely recognized data transfer speed units.

What Is This Tool?

This online converter transforms data transfer rates from IDE (PIO mode 2), an older CPU-driven transfer specification for IDE devices, into megabyte per second using the decimal SI definition. It helps users compare vintage drive speeds with current standards easily.

How to Use This Tool?

Enter the value in IDE (PIO mode 2) units that you want to convert.
Select the target unit as megabyte/second (SI def.).
Click 'Convert' to see the equivalent data transfer rate in MB/s (SI).

Key Features

Converts legacy IDE (PIO mode 2) transfer rates to megabyte per second (SI units).
Supports comparison of old hardware transfer speeds with modern digital throughput metrics.
Browser-based and easy to use without requiring installation.

Examples

2 IDE (PIO mode 2) equals 16.6 megabyte/second (SI def.).
0.5 IDE (PIO mode 2) equals 4.15 megabyte/second (SI def.).

Common Use Cases

Interpreting legacy BIOS or firmware drive timing for older IDE drives.
Comparing legacy IDE device performance with modern storage speed standards.
Diagnosing vintage PC hardware or fallback modes when DMA is not used.

Tips & Best Practices

Use this tool to bridge legacy hardware specifications with current digital data rate units.
Remember megabyte/second (SI def.) uses decimal-based units, which differ from binary-based units like MiB/s.
Check performance context since IDE PIO mode 2 rates represent theoretical maxima, not sustained speeds.

Limitations

IDE (PIO mode 2) rates reflect maximum theoretical values and might not indicate actual transfer speeds.
Megabyte/second SI units differ from binary-based measurements, potentially causing confusion when comparing with MiB/s.
This converter mainly applies to legacy storage technology and not modern, faster interfaces.

Key Terminology

IDE (PIO mode 2): A legacy ATA/IDE interface timing mode that defines CPU-driven data transfer rates for older storage devices.
Megabyte/second (SI def.): A unit representing one million bytes transferred per second, used to quantify data transfer rate in decimal units.
PIO (Programmed Input/Output): A data transfer method where the CPU controls data movement without using direct memory access (DMA).

Quick Knowledge Check

What does IDE (PIO mode 2) measure?

Modern SSD sequential speed

Legacy CPU-driven data transfer timing

Network transfer rate over Ethernet

What is the equivalent of 1 IDE (PIO mode 2) in megabyte/second (SI def.)?

1.0 MB/s

8.3 MB/s

10 MB/s

Why might megabyte/second (SI def.) differ from MiB/s?

Because SI units use decimal (base 10) while MiB/s uses binary (base 2)

Because MiB/s is always larger than MB/s

Because megabyte/second is used only for network speeds
