What Is This Tool?
This tool converts data transfer values from SCSI (Ultra-2), a modern parallel SCSI standard, to IDE (PIO mode 2), a legacy ATA/IDE CPU-driven data transfer mode, helping users compare performance metrics between different storage interface technologies.
How to Use This Tool?
-
Enter the amount of data transfer in SCSI (Ultra-2) units
-
Select IDE (PIO mode 2) as the target unit for conversion
-
Click convert to obtain the equivalent data transfer value in IDE (PIO mode 2)
Key Features
-
Converts transfer rates from SCSI (Ultra-2) to IDE (PIO mode 2) using a specific conversion rate
-
Supports understanding and diagnostics of data transfer in legacy and modern hardware
-
Browser-based and easy to use without installation
Examples
-
1 SCSI (Ultra-2) equals approximately 9.64 IDE (PIO mode 2)
-
5 SCSI (Ultra-2) equals approximately 48.19 IDE (PIO mode 2)
Common Use Cases
-
Comparing data transfer speed between parallel SCSI interfaces and legacy IDE modes
-
Assessing compatibility or performance issues in mixed hardware setups
-
Configuring or diagnosing legacy BIOS drive timing for older IDE drives
Tips & Best Practices
-
Ensure the context of hardware environments to apply the conversion appropriately
-
Understand that this conversion provides theoretical values and real-world performance may differ
-
Use the tool to support legacy system maintenance and troubleshooting
Limitations
-
Conversions reflect nominal transfer rates and may not represent actual hardware performance
-
IDE (PIO mode 2) is outdated with much lower speed compared to modern interfaces
-
Differences in protocol and bus design mean these units measure distinct aspects of data transfer
Frequently Asked Questions
-
What does this conversion rate mean?
-
It shows how many IDE (PIO mode 2) transfer units equal one SCSI (Ultra-2) unit, helping compare data transfer performance.
-
Is IDE (PIO mode 2) still used today?
-
IDE (PIO mode 2) is a legacy mode mostly relevant for older devices and troubleshooting vintage hardware.
-
Can I use this tool for exact performance measurement?
-
No, the tool provides theoretical conversions; actual performance depends on many hardware factors.
Key Terminology
-
SCSI (Ultra-2)
-
A parallel Small Computer System Interface standard that uses Low Voltage Differential signaling for improved data transfer performance and longer cables.
-
IDE (PIO mode 2)
-
A legacy ATA/IDE CPU-driven timing specification defining programmed I/O cycle transfers between host and storage.
-
Data Transfer
-
The process of moving data between devices or components within a computing environment.
