What Is This Tool?
This converter allows users to convert data transfer rates from the SCSI (LVD Ultra160) interface to the IDE (PIO mode 4) timing mode. It helps compare performance metrics between these legacy storage protocols frequently encountered in IT infrastructure and retro-computing.
How to Use This Tool?
-
Enter the data transfer value in SCSI (LVD Ultra160) units
-
Select the output unit as IDE (PIO mode 4)
-
Submit the conversion request to receive the equivalent value
-
Use the results to compare performance or plan system compatibility
Key Features
-
Converts SCSI (LVD Ultra160) bandwidth to equivalent IDE (PIO mode 4) throughput values
-
Uses established conversion rates based on theoretical maximum data-transfer rates
-
Supports benchmarking and migration planning for legacy storage devices
-
Browser-based and easy to use with no installation required
Examples
-
1 SCSI (LVD Ultra160) equals approximately 9.64 IDE (PIO mode 4)
-
5 SCSI (LVD Ultra160) corresponds to about 48.19 IDE (PIO mode 4) using the conversion factor
Common Use Cases
-
Benchmarking legacy storage device performance across different interface standards
-
Planning migrations by comparing data throughput between high-speed SCSI and older IDE modes
-
Diagnosing and configuring legacy IDE drives or SCSI storage in older servers
-
Supporting retro-computing and industrial systems that rely on historical storage protocols
Tips & Best Practices
-
Use the conversion values as rough estimates for comparing legacy storage performance
-
Consider real-world overhead and CPU load factors when interpreting results
-
Combine this tool’s output with other diagnostics for comprehensive system analysis
-
Regularly verify device specifications as actual throughput may vary from theoretical rates
Limitations
-
Conversion shows theoretical maximum throughput, excluding real-world operational factors
-
CPU-driven IDE (PIO mode 4) performance involves overhead, making direct equivalence approximate
-
Does not reflect the physical interface characteristics or efficiency differences between buses
Frequently Asked Questions
-
What does SCSI (LVD Ultra160) measure?
-
SCSI (LVD Ultra160) specifies a parallel SCSI interface bandwidth up to 160 MB/s using Low Voltage Differential signalling for storage device data transfers.
-
Why convert from SCSI (LVD Ultra160) to IDE (PIO mode 4)?
-
Conversion helps compare legacy storage device performance and assists in migration or compatibility planning between different interface standards.
-
Is the conversion exact in practical use?
-
No, the conversion reflects theoretical maximum speeds and does not account for CPU load or bus efficiency, so actual data transfer can differ.
Key Terminology
-
SCSI (LVD Ultra160)
-
A parallel SCSI interface with Low Voltage Differential signalling providing up to 160 MB/s throughput for storage devices.
-
IDE (PIO mode 4)
-
An ATA/IDE Programmed Input/Output timing mode where CPU controls data transfers, with a maximum theoretical throughput near 16.7 MB/s.
-
Data Transfer Rate
-
The speed at which data is transferred between devices, typically measured in megabytes per second (MB/s).
