What Is This Tool?

This tool converts data transfer rates between SCSI (Async), which uses asynchronous transfer mode, and IDE (UDMA-66), a Parallel ATA transfer mode. It helps translate performance metrics of legacy storage devices for applications such as benchmarking, configuration, and troubleshooting.

How to Use This Tool?

  • Enter the data transfer rate value in SCSI (Async) units.
  • Select SCSI (Async) as the source unit and IDE (UDMA-66) as the target unit.
  • Click convert to see the equivalent value in IDE (UDMA-66) units.
  • Use the results for benchmarking or configuring legacy storage devices.

Key Features

  • Converts from SCSI (Async), an asynchronous SCSI transfer mode.
  • Converts to IDE (UDMA-66), a Parallel ATA transfer mode with burst rates up to 66.7 MB/s.
  • Facilitates comparisons of legacy SCSI and IDE device transfer rates.
  • Useful for benchmarking, troubleshooting, and configuration of older hardware.
  • Browser-based and easy to use without additional software.

Examples

  • 10 SCSI (Async) equals approximately 0.227 IDE (UDMA-66).
  • 100 SCSI (Async) converts to about 2.273 IDE (UDMA-66).

Common Use Cases

  • Benchmarking throughput of legacy storage devices in SCSI asynchronous mode.
  • Configuring and testing embedded or retrocomputing systems with asynchronous SCSI.
  • Verifying maximum transfer rates of older PATA (IDE) drives using IDE (UDMA-66).
  • Diagnosing transfer errors and performance on legacy IDE systems.
  • Comparing or translating legacy SCSI asynchronous rates to IDE burst capabilities.

Tips & Best Practices

  • Confirm device and cable compatibility before interpreting conversion results.
  • Use the conversion as a nominal guideline, allowing for device and protocol differences.
  • Validate transfer rates with physical benchmarks for accurate performance assessment.
  • Apply this tool primarily for retrocomputing, legacy hardware troubleshooting, and archival purposes.

Limitations

  • Conversion reflects theoretical rates and may not represent actual sustained speeds.
  • Asynchronous transfer nature and protocol overhead limit direct performance equivalence.
  • Real-world results depend on device implementations, cable quality, and controller support.

Frequently Asked Questions

What does SCSI (Async) indicate?
It refers to the asynchronous data transfer mode of SCSI devices where data exchange relies on request/acknowledge handshakes without a shared clock.

What is IDE (UDMA-66)?
IDE (UDMA-66) is a Parallel ATA transfer mode that defines a maximum raw data rate of 66.7 MB/s and requires specific cabling and hardware support.

Why convert from SCSI (Async) to IDE (UDMA-66)?
To compare or translate data rates between legacy SCSI and PATA devices, useful for benchmarking, configuration, and troubleshooting.

Can conversion results be used for precise speed measurements?
No, due to protocol and hardware differences, the conversion provides nominal values that might not reflect sustained transfer speeds.

Key Terminology

SCSI (Async)
An asynchronous data transfer mode of the SCSI protocol using request/acknowledge handshakes instead of a shared clock.
IDE (UDMA-66)
A Parallel ATA transfer mode supporting up to 66.7 MB/s burst data rates requiring 80-conductor cables and compatible devices.
Data Transfer Rate
The speed at which data is moved from one device or medium to another, often measured in megabytes per second.
