What Is This Tool?
This converter allows users to translate data transfer throughput values from IDE (UDMA mode 3), a Parallel ATA signaling mode, into equivalent SCSI (LVD Ultra160) rates used by parallel SCSI interfaces. It is especially useful for comparing performance in legacy computing and storage systems.
How to Use This Tool?
-
Enter the data transfer rate value in IDE (UDMA mode 3) units.
-
Select IDE (UDMA mode 3) as the source unit and SCSI (LVD Ultra160) as the target unit.
-
Click the convert button to see the equivalent SCSI (LVD Ultra160) value.
-
Use the result to compare or document legacy storage performance.
Key Features
-

-
Supports legacy storage interface performance comparison.
-
Easy to use with simple input and conversion steps.
-
Browser-based and accessible for IT professionals managing older hardware.
-
Provides clear examples to illustrate conversions.
Examples
-
2 IDE (UDMA mode 3) units convert to 0.625 SCSI (LVD Ultra160).
-
4 IDE (UDMA mode 3) units convert to 1.25 SCSI (LVD Ultra160).
Common Use Cases
-
Comparing throughput of legacy PATA/IDE hard drives and parallel SCSI devices.
-
Assisting in troubleshooting or refurbishing older computer and storage systems.
-
Documenting and specifying drive transfer rates in system datasheets.
-
Planning IT system migrations involving legacy storage interfaces.
-
Evaluating bandwidth requirements for tape drives and RAID controllers using SCSI.
Tips & Best Practices
-
Always double-check which unit standard applies to your storage device.
-
Use this conversion to aid in system compatibility and performance assessments.
-
Consider device-specific factors beyond theoretical throughput for real-world accuracy.
-
Apply this tool mainly for legacy hardware, not current technology benchmarks.
-
Refer to system documentation to confirm transfer modes and supported interfaces.
Limitations
-
Conversion is based on theoretical maximum throughputs and excludes real-world inefficiencies.
-
Does not account for overhead, cable quality, or system bottlenecks affecting performance.
-
Applies only to legacy data transfer standards and may not reflect modern technologies.
