What Is This Tool?
This converter tool allows you to translate data transfer values from the IDE (PIO mode 3) standard to the SCSI (Ultra-3) standard, facilitating comparisons between legacy CPU-driven ATA devices and modern enterprise-class SCSI storage interfaces.
How to Use This Tool?
-
Enter the value in IDE (PIO mode 3) units you want to convert
-
Select IDE (PIO mode 3) as the source unit and SCSI (Ultra-3) as the target unit
-
Click the convert button to obtain the equivalent value in SCSI (Ultra-3)
-
Use the converted result for performance analysis or system compatibility checks
Key Features
-
Converts data transfer rates from IDE (PIO mode 3) to SCSI (Ultra-3) units
-
Based on theoretical maximum throughput values for accurate comparison
-
Browser-based and easy to use with no installation required
-
Supports legacy and modern storage interface evaluations
-
Provides example calculations for clarity
Examples
-
5 IDE (PIO mode 3) = 0.346875 SCSI (Ultra-3)
-
10 IDE (PIO mode 3) = 0.69375 SCSI (Ultra-3)
Common Use Cases
-
Comparing data transfer speeds between legacy ATA and modern SCSI storage systems
-
Evaluating performance in retrocomputing and historical storage mode testing
-
Designing or diagnosing enterprise storage arrays and backup systems
-
Bridging compatibility and throughput understanding in embedded or industrial setups
Tips & Best Practices
-
Use this conversion for theoretical performance comparison rather than exact real-world speeds
-
Consider hardware and protocol differences when interpreting results
-
Employ the tool for compatibility checks in IT infrastructure and data center environments
-
Leverage example calculations to understand the conversion process
Limitations
-
Conversion is based on theoretical maximum throughput values, not observed sustained rates
-
Differences in protocols and hardware mean the results are conceptual estimates
-
Actual data transfer speeds vary due to CPU load, bus usage, and device implementation
Frequently Asked Questions
-
What does IDE (PIO mode 3) represent?
-
IDE (PIO mode 3) is a CPU-driven programmed I/O transfer mode for Parallel ATA/IDE devices, with a theoretical max throughput of about 11.1 MB/s.
-
What is SCSI (Ultra-3)?
-
SCSI (Ultra-3) is a parallel Small Computer System Interface standard used for block-level data transfers between hosts and storage devices, common in enterprise storage.
-
Why convert between IDE (PIO mode 3) and SCSI (Ultra-3)?
-
Users convert to compare data transfer rates across legacy and modern storage technologies for performance evaluation and compatibility checking.
