What Is This Tool?

This tool converts data transfer values from SCSI (Async)—the asynchronous transfer mode used by legacy SCSI devices—to IDE (UDMA mode 2), an Ultra DMA transfer mode for Parallel ATA interfaces. It helps users interpret and compare performance metrics between these two distinct legacy storage technologies.

How to Use This Tool?

  • Enter the data transfer value measured in SCSI (Async) units
  • Select the target unit IDE (UDMA mode 2) for conversion
  • Click convert to obtain the equivalent data rate
  • Use the result for performance analysis, benchmarking, or device configuration

Key Features

  • Converts data transfer units from SCSI (Async) to IDE (UDMA mode 2)
  • Based on standard conversion formula relating throughput approximations
  • Supports benchmarking and troubleshooting of legacy SCSI and ATA/IDE devices
  • Browser-based and easy to use for embedded and retrocomputing contexts
  • Facilitates comparison of asynchronous SCSI throughput with synchronous ATA/IDE rates

Examples

  • Convert 10 SCSI (Async) units: 10 × 0.0454545455 = 0.454545455 IDE (UDMA mode 2)
  • Convert 100 SCSI (Async) units: 100 × 0.0454545455 = 4.54545455 IDE (UDMA mode 2)

Common Use Cases

  • Benchmark legacy SCSI devices operating asynchronously against IDE drives
  • Troubleshoot timing and compatibility issues on SCSI and PATA controllers
  • Configure retro or embedded systems using asynchronous SCSI or IDE UDMA mode 2
  • Compare throughput performance between asynchronous SCSI and ATA/IDE modes
  • Analyze legacy storage device data transfer rates for diagnostics

Tips & Best Practices

  • Remember the conversion is approximate due to protocol and signaling differences
  • Use conversion results primarily for benchmarking and comparative purposes
  • Consider device response times and bus arbitration impacts on real throughput
  • Double-check compatibility settings when configuring legacy SCSI or IDE devices
  • Utilize this tool in embedded or retrocomputing environments for accurate correlation

Limitations

  • Conversion reflects theoretical or typical throughput, not accounting for real overhead or delays
  • SCSI (Async) and IDE (UDMA mode 2) use fundamentally different transfer protocols
  • Direct equivalence of throughput is approximate and may vary depending on hardware context

Frequently Asked Questions

What does SCSI (Async) represent in data transfer?
SCSI (Async) denotes asynchronous data-transfer mode of the SCSI protocol where data exchange uses request/acknowledge handshakes without a shared clock.

What is IDE (UDMA mode 2) used for?
IDE (UDMA mode 2) is an Ultra DMA transfer mode for Parallel ATA interfaces, enabling synchronous data transfers with a maximum theoretical rate of about 33.3 MB/s.

Why is the conversion between SCSI (Async) and IDE (UDMA mode 2) approximate?
Because the two standards use different signaling and protocols, and real-world performance may be affected by factors not reflected in the simple conversion rate.

Key Terminology

SCSI (Async)
An asynchronous data transfer mode of the SCSI protocol using request/acknowledge handshakes rather than a shared clock.
IDE (UDMA mode 2)
An Ultra DMA transfer mode for Parallel ATA interfaces with a synchronous signaling profile supporting about 33.3 MB/s throughput.
Conversion Rate
The factor used to translate data transfer values from one unit (SCSI Async) to another (IDE UDMA mode 2), here approximately 0.0454545455.
