What Is This Tool?
This converter helps you translate data transfer values from IDE (PIO mode 2), a legacy ATA/IDE interface timing mode, into SCSI (Fast Ultra), a faster parallel SCSI signalling mode. It supports users working with legacy hardware and modern storage solutions to assess and compare transfer capabilities.
How to Use This Tool?
-
Enter the value in IDE (PIO mode 2) units that you want to convert
-
Select IDE (PIO mode 2) as the source unit and SCSI (Fast Ultra) as the target
-
Click on the convert button to see the equivalent SCSI (Fast Ultra) value
-
Use the results to compare transfer speeds or assist in hardware configuration
Key Features
-
Converts data transfer units between IDE (PIO mode 2) and SCSI (Fast Ultra)
-
Simple interface for quick input and output
-
Helps evaluate legacy and modern storage performance
-
Browser-based tool requiring no installations
-
Useful for IT professionals dealing with varied storage technologies
Examples
-
5 IDE (PIO mode 2) converts to 2.075 SCSI (Fast Ultra)
-
10 IDE (PIO mode 2) converts to 4.15 SCSI (Fast Ultra)
Common Use Cases
-
Configuring legacy BIOS settings for older IDE hard drives
-
Diagnosing performance on vintage PCs reverting from DMA to PIO mode
-
Comparing transfer speeds when upgrading from IDE to SCSI in storage environments
-
Connecting high-performance RAID controllers or tape backup devices
-
Evaluating compatibility in environments mixing legacy and modern storage hardware
Tips & Best Practices
-
Use this tool primarily for legacy hardware diagnostics and upgrade planning
-
Remember the conversion reflects theoretical maximum speeds, not actual performance
-
Combine conversion results with hardware specs for accurate system assessments
-
Keep firmware and drivers updated for optimal device performance
-
Handle legacy and modern storage interfaces based on their respective timing standards
Limitations
-
Conversion shows theoretical maximum transfer rates and may not match real-world speeds
-
IDE (PIO mode 2) is an older mode and generally slower than modern technologies
-
Direct equivalence is mainly useful for historical comparisons or specific diagnostic needs
Frequently Asked Questions
-
What does IDE (PIO mode 2) mean?
-
IDE (PIO mode 2) refers to a legacy ATA/IDE interface timing specification for CPU-driven data transfers using programmed I/O cycles.
-
What is SCSI (Fast Ultra) used for?
-
SCSI (Fast Ultra) is a parallel signalling mode combining Fast and Ultra SCSI extensions for higher throughput on devices like RAID controllers and tape libraries.
-
Why convert between IDE (PIO mode 2) and SCSI (Fast Ultra)?
-
Users convert between these units to compare transfer speeds and ensure compatibility when working with legacy and modern storage hardware.
