What Is This Tool?

This tool converts data transfer rates from SCSI (Sync), a synchronous SCSI protocol mode, to IDE (UDMA mode 1), an Ultra DMA transfer mode of the Parallel ATA interface. It helps compare and interpret throughput between these legacy storage interfaces.

How to Use This Tool?

  • Enter the data transfer value in SCSI (Sync) units.
  • Choose SCSI (Sync) as the input unit and IDE (UDMA mode 1) as the output unit.
  • Click convert to get the corresponding value in IDE (UDMA mode 1).
  • Review the result to compare different storage interface throughput rates.

Key Features

  • Converts data rates from SCSI (Sync) to IDE (UDMA mode 1).
  • Based on negotiated parameters and defined standards for transfer modes.
  • Supports legacy storage hardware and performance comparisons.
  • Browser-based and easy to use without requiring installation.
  • Provides examples for clear understanding of conversions.

Examples

  • 5 SCSI (Sync) equals 1 IDE (UDMA mode 1) after conversion.
  • 10 SCSI (Sync) equals 2 IDE (UDMA mode 1) based on the conversion rate.

Common Use Cases

  • Comparing transfer speeds between synchronous SCSI devices and IDE drives.
  • Diagnosing and setting BIOS or drive transfer modes on older PCs.
  • Benchmarking or troubleshooting data rates in legacy storage systems.
  • Supporting vintage computer restoration and archival storage environments.
  • Interpreting throughput limits when upgrading or maintaining legacy hardware.

Tips & Best Practices

  • Always verify hardware compatibility when comparing different interface types.
  • Use the tool for theoretical maximum rates; actual speeds might be lower.
  • Combine conversion insights with diagnostics to troubleshoot connection issues.
  • Consider protocol differences affecting timing and error handling.
  • Keep legacy system documentation handy to understand mode parameters.

Limitations

  • Conversion reflects theoretical maximum speeds, not actual throughput.
  • SCSI (Sync) and IDE (UDMA mode 1) use different protocols and timing methods.
  • Direct practical equivalence between the two modes is limited.
  • Modern storage technologies have surpassed both interfaces, limiting use today.
  • Variable factors like hardware condition and cables impact real-world results.

Frequently Asked Questions

What does SCSI (Sync) mode mean?
SCSI (Sync) is a synchronous transfer mode where data transfers occur in sync with a negotiated clock, allowing higher throughput and consistent timing than asynchronous transfers.

What is IDE (UDMA mode 1)?
IDE (UDMA mode 1) is an Ultra DMA transfer mode for Parallel ATA devices, offering a maximum raw transfer rate around 25 MB/s, commonly used for older PATA drives.

Why convert from SCSI (Sync) to IDE (UDMA mode 1)?
Conversion helps compare transfer rates across different legacy storage protocols and assists in diagnosing or benchmarking older hardware systems.

Can I use this conversion for modern storage devices?
No, this tool is suited for legacy interfaces, as modern storage devices use more advanced protocols surpassing SCSI (Sync) and IDE (UDMA mode 1).

Key Terminology

SCSI (Sync)
A synchronous SCSI transfer mode using a negotiated clock for higher throughput and consistent timing.
IDE (UDMA mode 1)
An Ultra DMA mode for Parallel ATA devices allowing up to roughly 25 MB/s transfer rates, used in older hardware.
Data transfer rate
The speed at which data is transmitted between devices, typically measured in bytes per second.
