What Is This Tool?

This converter tool allows users to convert data transfer rates between IDE (UDMA-66) and SCSI (Ultra-2) standards, which represent legacy Parallel ATA and parallel SCSI interfaces respectively. It helps compare the maximum theoretical burst speeds of these storage technologies.

How to Use This Tool?

  • Enter the data transfer value in IDE (UDMA-66) units.
  • Select IDE (UDMA-66) as the source unit and SCSI (Ultra-2) as the target unit.
  • Click the convert button to see the equivalent data rate in SCSI (Ultra-2).

Key Features

  • Supports conversion between IDE (UDMA-66) and SCSI (Ultra-2) data transfer units.
  • Uses established conversion rate based on maximum theoretical data rates.
  • Browser-based and easy to use without any software installation.
  • Useful for IT legacy system maintenance and data center storage configuration.
  • Helps compare and integrate data transfer rates of different legacy storage protocols.

Examples

  • 1 IDE (UDMA-66) equals 0.825 SCSI (Ultra-2).
  • 10 IDE (UDMA-66) converts to 8.25 SCSI (Ultra-2).

Common Use Cases

  • Verifying burst throughput of older PATA (IDE) hard drives and optical drives.
  • Comparing data transfer rates between legacy Parallel ATA and parallel SCSI systems.
  • Configuring storage arrays and RAID controllers with mixed interface drives.
  • Interpreting benchmark results and diagnosing transfer errors on legacy systems.
  • Supporting enterprise and backup storage device setup in data centers.

Tips & Best Practices

  • Ensure correct unit selection when inputting values to avoid errors.
  • Use this conversion primarily for legacy hardware configurations and diagnostics.
  • Consider real-world factors like protocol overhead which affect actual transfer speeds.
  • Refer to this tool when upgrading or integrating mixed legacy storage devices.

Limitations

  • Conversion rate reflects maximum theoretical speeds, not real-world performance.
  • Actual transfer rates vary due to protocol overhead and signaling differences.
  • Relevant mainly for legacy PATA and parallel SCSI systems, not modern interfaces.
  • Does not account for new SCSI variants or SATA/SAS protocols.

Frequently Asked Questions

What does IDE (UDMA-66) represent?
IDE (UDMA-66) defines a Parallel ATA transfer mode with a maximum raw data rate of 66.7 MB/s, used for legacy PATA storage devices.

What is SCSI (Ultra-2)?
SCSI (Ultra-2) is a parallel Small Computer System Interface standard using Low Voltage Differential signaling to provide improved data transfer performance for block storage devices.

Can this converter be used for modern SATA or SAS devices?
No, this conversion tool is intended for legacy hardware and does not apply to modern SATA, SAS, or newer SCSI variants.

Key Terminology

IDE (UDMA-66)
A Parallel ATA transfer mode with a maximum theoretical data transfer rate of 66.7 MB/s, requiring an 80-conductor PATA cable.
SCSI (Ultra-2)
A parallel Small Computer System Interface standard that uses Low Voltage Differential signaling to improve data transfer performance and cable length.
Data Transfer Rate
The speed at which data is transmitted from one device to another, usually measured in megabytes per second.
