What Is This Tool?
This converter allows users to translate data transfer values between SCSI (LVD Ultra160), a high-throughput parallel SCSI interface standard, and IDE (PIO mode 1), a CPU-driven transfer mode for PATA devices. It helps compare performance metrics of different legacy storage technologies.
How to Use This Tool?
-
Enter the data transfer value in SCSI (LVD Ultra160) units
-
Select the target unit as IDE (PIO mode 1)
-
Click the convert button to see the equivalent value
-
Use the resulting value to compare or adapt performance between legacy interfaces
Key Features
-
Browser-based and easy to use for quick unit conversions
-
Converts data transfer rates from SCSI (LVD Ultra160) to IDE (PIO mode 1)
-
Supports legacy IT and storage device benchmarking and performance comparison
-
Provides a direct conversion ratio based on theoretical maximum throughput
-
Useful for assessing compatibility and planning migration between hardware standards
Examples
-
1 SCSI (LVD Ultra160) equals approximately 30.77 IDE (PIO mode 1)
-
5 SCSI (LVD Ultra160) converts to about 153.85 IDE (PIO mode 1)
Common Use Cases
-
Specifying maximum data-transfer rates for internal disk arrays in legacy servers
-
Comparing throughput of tape drives and backup systems using parallel SCSI
-
Configuring or diagnosing legacy PATA hard drives and optical drives
-
Benchmarking data-transfer performance on vintage or embedded systems
-
Supporting firmware development where CPU-driven transfers are necessary
Tips & Best Practices
-
Use the converter for theoretical maximum throughput comparisons rather than exact performance prediction
-
Consider system-specific factors like CPU load and device limitations when interpreting results
-
Apply the tool mainly for legacy hardware compatibility and migration planning
-
Remember the difference in hardware architectures when assessing direct equivalence
-
Use multiple measurements and testing methods for comprehensive performance evaluation
Limitations
-
Conversion shows theoretical maximum rates without reflecting CPU overhead in PIO mode
-
Does not account for device-specific or environmental factors affecting actual performance
-
SCSI (LVD Ultra160) and IDE (PIO mode 1) use differing protocols and hardware, impacting direct comparison accuracy
Frequently Asked Questions
-
What does SCSI (LVD Ultra160) represent?
-
It is a parallel SCSI interface standard using Low Voltage Differential signaling with up to 160 MB/s bandwidth, indicating maximum sustained data transfer between host adapters and storage devices.
-
What is IDE (PIO mode 1)?
-
IDE (PIO mode 1) is a CPU-controlled data transfer mode for Parallel ATA devices, offering lower throughput with higher CPU overhead compared to DMA modes.
-
Why convert between these two units?
-
Conversion helps compare or adapt data transfer rates when dealing with legacy server systems, backup solutions, or firmware development involving different storage interface standards.
Key Terminology
-
SCSI (LVD Ultra160)
-
A parallel SCSI interface standard using Low Voltage Differential signaling with a maximum throughput of 160 MB/s.
-
IDE (PIO mode 1)
-
A Programmed Input/Output mode for PATA devices where the CPU controls data transfer cycles, typically with higher CPU load.
-
Data Transfer Rate
-
The speed at which data is transmitted between devices, often measured in megabytes per second (MB/s).
