What does IDE (PIO mode 1) mean?

IDE (PIO mode 1) is a CPU-driven data transfer mode used by legacy PATA devices that controls each transfer cycle directly via the host processor.

How does SCSI (Async) data transfer work?

SCSI (Async) uses asynchronous handshakes for data exchange, relying on request and acknowledge signals without a shared clock, affecting throughput by response timing.

Why convert between IDE (PIO mode 1) and SCSI (Async)?

Converting these units helps compare or analyze data transfer speeds of legacy devices operating under different protocols, useful in benchmarking and troubleshooting.

What Is This Tool?

This converter transforms data transfer values from IDE (PIO mode 1), a CPU-controlled mode for PATA devices, to SCSI (Async), an asynchronous data-transfer mode of SCSI devices. It helps compare legacy storage device performance using standard conversion rates.

How to Use This Tool?

Enter the value in IDE (PIO mode 1) unit that you want to convert
Select IDE (PIO mode 1) as the source unit and SCSI (Async) as the target unit
Start the conversion to get the equivalent SCSI (Async) value
Use the result to compare or analyze data transfer rates across legacy devices

Key Features

Supports conversion between IDE (PIO mode 1) and SCSI (Async) units
Uses defined standard conversion rate without assumptions about hardware variability
Useful for benchmarking, troubleshooting, and configuring legacy and embedded systems
Browser-based and easy to operate without technical setup

Examples

2 IDE (PIO mode 1) equals 6.9333333334 SCSI (Async)
5 IDE (PIO mode 1) equals 17.3333333335 SCSI (Async)

Common Use Cases

Configuring or diagnosing legacy PATA hard drives and optical drives in older equipment
Benchmarking data-transfer performance on vintage or embedded systems using PIO modes
Troubleshooting timing and compatibility issues on SCSI buses in asynchronous mode
Testing and configuring embedded or retrocomputing systems using asynchronous SCSI

Tips & Best Practices

Ensure stable operating conditions when applying conversion results
Use conversion values primarily for benchmarking and diagnostic purposes
Avoid relying on results for precise throughput without considering device-specific factors
Double-check unit selections before conversion to avoid errors

Limitations

Conversion does not account for hardware-specific bus arbitration or response time differences
CPU overhead and asynchronous behaviors may cause real throughput to vary
Values are approximate and best suited for comparative analysis rather than exact measurement
