What Is This Tool?
This converter allows you to translate data transfer values from IDE (PIO mode 3), a CPU-driven parallel ATA mode, to SCSI (Fast Wide), a wider and faster SCSI-2 interface. It helps compare performance and compatibility between these two legacy storage transfer standards.
How to Use This Tool?
-
Enter the numerical value in IDE (PIO mode 3) units.
-
Select IDE (PIO mode 3) as the source unit and SCSI (Fast Wide) as the target unit.
-
Click convert to see the equivalent data transfer rate in SCSI (Fast Wide).
Key Features
-
Converts data transfer rates from IDE (PIO mode 3) to SCSI (Fast Wide)
-
Browser-based and simple to use interface
-
Useful for legacy system performance comparison and retrocomputing
-
Includes conversion examples for quick understanding
Examples
-
2 IDE (PIO mode 3) equals 1.11 SCSI (Fast Wide)
-
5 IDE (PIO mode 3) equals 2.775 SCSI (Fast Wide)
Common Use Cases
-
Evaluating performance differences between CPU-driven IDE transfer modes and faster SCSI buses
-
Translating data rates for legacy servers and embedded systems using both interfaces
-
Benchmarking and maintenance of older hardware in data centers and industrial environments
Tips & Best Practices
-
Use the tool to estimate and compare legacy data transfer capabilities.
-
Consider physical and implementation factors like cable quality and signaling when interpreting results.
-
Apply conversions to support upgrade planning and compatibility assessments.
Limitations
-
Conversion reflects theoretical maximums and does not account for overhead or real-world conditions.
-
CPU-driven nature of IDE (PIO mode 3) can cause practical bottlenecks beyond raw throughput.
-
SCSI (Fast Wide) throughput varies with hardware implementation details, making exact conversions approximate.
