What does the conversion rate between SCSI (Ultra-2) and IDE (PIO mode 0) represent?

It represents the theoretical throughput ratio comparing the data transfer speeds of the two standards, helping users understand their relative performance.

Can this converter be used to improve storage device speeds?

No, this tool is for comparison and understanding differences in data transfer rates, not for enhancing actual hardware performance.

Why is IDE (PIO mode 0) considered slow compared to SCSI (Ultra-2)?

IDE (PIO mode 0) relies on CPU-driven data transfers without DMA, resulting in slower maximum throughput and less efficient operation compared to SCSI (Ultra-2).

Tips & Best Practices

Always verify the context of conversion, as it reflects throughput ratios, not protocol efficiency
Use the tool for comparing theoretical speeds rather than real-world performance
Refer to examples to confirm proper unit input and output interpretation
Consider hardware limitations when using IDE (PIO mode 0) for modern applications
Leverage the conversion for troubleshooting legacy storage systems

Limitations

Conversion only reflects throughput ratios without accounting for protocol efficiency
IDE (PIO mode 0) is limited by CPU involvement and the slowest timing mode
Results may not represent actual performance under real-world conditions
Not suitable for evaluating modern high-performance storage solutions
