What Is This Tool?

This tool enables conversion of data transfer rates from SCSI (Async), an asynchronous SCSI protocol mode, to IDE (UDMA mode 4), a Parallel ATA Ultra DMA transfer standard.

How to Use This Tool?

  • Enter the value measured in SCSI (Async) data transfer units.
  • Select the target unit IDE (UDMA mode 4) for conversion.
  • Execute the conversion to see the equivalent transfer rate.
  • Use the results for configuring or benchmarking legacy systems.
  • Refer to examples for guidance on calculation.

Key Features

  • Converts between two specific legacy data transfer units: SCSI (Async) and IDE (UDMA mode 4).
  • Based on defined conversion rate and formula using standard protocol information.
  • Supports comparison and translation of transfer rates for benchmarking and troubleshooting.
  • Browser-based and simple to use without requiring additional software.
  • Includes examples illustrating typical conversion calculations.

Examples

  • 5 SCSI (Async) equals 0.1136363635 IDE (UDMA mode 4) based on the conversion formula.
  • 10 SCSI (Async) converts to 0.227272727 IDE (UDMA mode 4) using the given rate.

Common Use Cases

  • Benchmarking or reporting throughput of older SCSI hardware operating asynchronously.
  • Troubleshooting handshake or compatibility issues in SCSI bus communications.
  • Configuring embedded or retro systems employing asynchronous SCSI connections.
  • Connecting and maintaining legacy IDE drives supporting Ultra DMA mode 4.
  • Testing DMA mode configurations in BIOS or firmware for vintage systems.
  • Data recovery and benchmarking of aging storage devices using either protocol.

Tips & Best Practices

  • Verify device capabilities before converting and using transfer rates.
  • Use the tool to support diagnostic and benchmarking tasks on legacy hardware.
  • Keep in mind the protocol differences for realistic expectations of throughput.
  • Cross-reference results with device specifications for accuracy.
  • Ensure reliable cabling such as 80-conductor IDE cables for UDMA modes.

Limitations

  • Conversion provides an approximation due to variability in SCSI (Async) throughput depending on device and bus behavior.
  • IDE (UDMA mode 4) rates represent theoretical maximums and may not reflect practical speeds.
  • Both units derive from older technologies and might not support current hardware standards.
  • Throughput differences can be influenced by system constraints and device response times.

Frequently Asked Questions

What does SCSI (Async) mean in data transfers?
SCSI (Async) denotes an asynchronous mode using request/acknowledge handshakes without a shared clock, influencing effective throughput based on device response and bus arbitration.

What is IDE (UDMA mode 4) used for?
IDE (UDMA mode 4), also known as Ultra DMA/66, is a Parallel ATA transfer mode supporting up to about 66.7 megabytes per second, often used with late 1990s and early 2000s PCs.

Why might conversion results vary between these units?
Because SCSI (Async) throughput depends on asynchronous handshake timing and IDE (UDMA mode 4) is a theoretical maximum transfer mode, actual speeds can differ due to hardware and system constraints.

Key Terminology

SCSI (Async)
An asynchronous data-transfer mode in SCSI using request/acknowledge handshakes without a shared clock, affecting effective throughput.
IDE (UDMA mode 4)
A Parallel ATA transfer mode also known as Ultra DMA/66, supporting data rates up to approximately 66.7 megabytes per second.
Conversion Rate
The numerical factor used to translate data transfer values from SCSI (Async) units to IDE (UDMA mode 4), approximately 0.0227.
