What Is This Tool?
This unit converter transforms data transfer rates from SCSI (Fast Wide), a legacy SCSI-2 interface mode, into equivalents in IDE (UDMA mode 4), an older Parallel ATA transfer mode. It helps users compare or migrate transfer speeds between these legacy storage standards, commonly used in vintage computing and hardware maintenance.
How to Use This Tool?
-
Enter the data transfer value measured in SCSI (Fast Wide)
-
Select SCSI (Fast Wide) as the input unit and IDE (UDMA mode 4) as the output unit
-
Click convert to obtain the equivalent transfer rate in IDE (UDMA mode 4)
-
Review the conversion result and apply it for system configuration or benchmarking
Key Features
-
Converts data rates between SCSI (Fast Wide) and IDE (UDMA mode 4)
-
Supports legacy storage interface standards used in servers, workstations, and PCs
-
Provides a browser-based easy-to-use interface for quick conversion
-
Includes practical examples for understanding conversion results
Examples
-
Convert 5 SCSI (Fast Wide) units to IDE (UDMA mode 4): results in approximately 1.515 IDE (UDMA mode 4)
-
Convert 10 SCSI (Fast Wide) units to IDE (UDMA mode 4): results in approximately 3.03 IDE (UDMA mode 4)
Common Use Cases
-
Comparing data transfer rates between legacy SCSI and IDE storage interfaces
-
Migrating hardware configurations involving mixed legacy devices
-
Evaluating performance for vintage servers, workstations, or embedded systems
-
Supporting data recovery and benchmarking of older storage devices
Tips & Best Practices
-
Ensure accurate input values corresponding to your hardware measurements
-
Consider hardware-specific factors like cable quality and device negotiation affecting throughput
-
Use this tool within legacy system contexts rather than modern storage environments
-
Consult device documentation to verify compatibility before relying on conversion results
Limitations
-
Theoretical maximum throughput may not reflect actual transfer rates due to hardware variations
-
Cable type, signal integrity, and device negotiation impact real-world performance
-
This converter applies only to legacy storage standards and may not suit modern technologies
-
Device compatibility issues might restrict achievable speeds despite conversions
Frequently Asked Questions
-
What is SCSI (Fast Wide)?
-
SCSI (Fast Wide) is a SCSI-2 interface mode combining 10 MHz Fast timing with a 16-bit data bus, supporting theoretical maximum throughput around 20 MB/s for certain implementations.
-
What does IDE (UDMA mode 4) represent?
-
IDE (UDMA mode 4), also known as Ultra DMA/66, is a Parallel ATA transfer mode capable of up to approximately 66.7 MB/s with an 80-conductor IDE cable.
-
Why convert between SCSI (Fast Wide) and IDE (UDMA mode 4)?
-
Users convert between these units to compare or migrate data transfer rates when managing legacy hardware, troubleshooting, or benchmarking older storage interfaces.
Key Terminology
-
SCSI (Fast Wide)
-
A SCSI-2 interface mode using Fast timing at 10 MHz with a 16-bit data bus to increase data throughput.
-
IDE (UDMA mode 4)
-
A Parallel ATA transfer mode, also called Ultra DMA/66, supporting maximum theoretical throughput near 66.7 MB/s.
-
Data Transfer Rate
-
The speed at which data is moved from one device to another, measured here in megabytes per second (MB/s).
