What Is This Tool?
This converter allows you to transform data transfer performance values from SCSI (Fast Ultra Wide), a legacy parallel interface mode, into IDE (PIO mode 4), a CPU-driven ATA/IDE timing mode. It helps compare and assess throughput across different legacy storage protocols.
How to Use This Tool?
-
Enter the value in SCSI (Fast Ultra Wide) units you want to convert
-
Select the desired output as IDE (PIO mode 4)
-
Click the convert button to see the equivalent value
Key Features
-
Converts SCSI (Fast Ultra Wide) transfer values to IDE (PIO mode 4) equivalents
-
Designed for legacy data transfer rate measurements and compatibility checks
-
Simple input and output for seamless user experience
Examples
-
1 SCSI (Fast Ultra Wide) equals approximately 2.41 IDE (PIO mode 4)
-
5 SCSI (Fast Ultra Wide) converts to about 12.05 IDE (PIO mode 4)
Common Use Cases
-
Evaluating performance differences when upgrading legacy storage systems
-
Ensuring interoperability between SCSI and IDE interfaces in older computing environments
-
Configuring or diagnosing legacy server and workstation storage hardware
Tips & Best Practices
-
Use the converter to compare throughput capabilities during system maintenance or upgrades
-
Consider device age and system architecture as they affect actual transfer speeds
-
Verify conversion results with practical benchmarking for critical applications
Limitations
-
Conversion reflects relative throughput performance, not physical storage units
-
Factors such as device condition, cabling, and bus overhead influence real-world speeds
-
IDE (PIO mode 4) is CPU-driven and typically slower than SCSI’s bus-mastered transfers
Frequently Asked Questions
-
What does SCSI (Fast Ultra Wide) represent?
-
It is a legacy parallel Small Computer System Interface mode that combines a wider data bus and faster signalling to provide higher sustained throughput.
-
What is IDE (PIO mode 4)?
-
IDE (PIO mode 4) is a CPU-controlled timing mode for ATA/IDE drives with a maximum theoretical throughput around 16.7 MB/s.
-
Why convert from SCSI (Fast Ultra Wide) to IDE (PIO mode 4)?
-
To understand differences in transfer performance and ensure compatibility when managing or upgrading legacy storage systems.
Key Terminology
-
SCSI (Fast Ultra Wide)
-
A legacy parallel interface mode with a wider data bus and faster signalling for increased data transfer throughput.
-
IDE (PIO mode 4)
-
A programmed input/output timing mode where the CPU controls data transfers for ATA/IDE storage devices.
-
Data Transfer Rate
-
The speed at which data is transferred between devices or components.
