What Is This Tool?
This tool facilitates the conversion of data transfer rates from IDE (PIO mode 3) storage mode to the modem speed classification of 2400 bits per second. It helps compare and translate data transfer capabilities between legacy storage interfaces and early modem speeds.
How to Use This Tool?
-
Enter the value in IDE (PIO mode 3) units you want to convert.
-
Select the target unit as modem (2400) for conversion.
-
Click convert to see the equivalent modem (2400) speed.
Key Features
-
Converts between IDE (PIO mode 3) and modem (2400) data transfer rates.
-
Based on established conversion rates defined by legacy standards.
-
Ideal for retrocomputing, compatibility testing, and performance comparison.
-
Browser-based and simple to use without installation.
Examples
-
1 IDE (PIO mode 3) equals 37000 modem (2400).
-
2 IDE (PIO mode 3) equals 74000 modem (2400).
Common Use Cases
-
Comparing modern or legacy hard drive transfer speeds to early modem rates.
-
Retrocomputing and emulator testing involving historic computing and communication standards.
-
Embedded system design requiring legacy device interfacing where DMA is unsupported.
Tips & Best Practices
-
Use the conversion to benchmark and compare old storage devices with modem speeds.
-
Leverage the tool for educational purposes in computer history research.
-
Understand the approximate nature of the conversion when applying results.
Limitations
-
Conversion is approximate; IDE throughput is raw device data rate while modem speed includes communication overhead.
-
Modem (2400) is a descriptive speed class, not an exact SI unit, with variable actual throughput.
-
IDE (PIO mode 3) uses CPU-driven transfer which may vary in real-world efficiency compared to theoretical rates.
Frequently Asked Questions
-
What does IDE (PIO mode 3) represent?
-
IDE (PIO mode 3) is a CPU-driven programmed transfer mode for Parallel ATA/IDE storage devices with a theoretical max throughput around 11.1 MB/s.
-
What is modem (2400) speed?
-
Modem (2400) denotes a data-transfer rate of 2400 bits per second, typical of early dial-up modem standards like ITU-T V.22bis.
-
Why convert IDE (PIO mode 3) to modem (2400)?
-
Users convert to compare and translate legacy storage interface speeds into early modem equivalents for retrocomputing or compatibility testing.
Key Terminology
-
IDE (PIO mode 3)
-
A CPU-driven programmed I/O transfer mode for Parallel ATA/IDE devices with a maximum raw data throughput about 11.1 MB/s.
-
Modem (2400)
-
A descriptive classification for data transfer speeds at 2400 bits per second, typically for early dial-up modems.
-
Data Transfer Rate
-
The speed at which data is moved from one place to another, measured here between storage device modes and modem speeds.
