What Is This Tool?
This unit converter allows users to translate data transfer speeds from the SCSI (LVD Ultra80) standard to the IDE (PIO mode 1) transfer mode. It helps in comparing performance and compatibility between high-speed SCSI devices and older PATA storage systems operating in CPU-driven transfer modes.
How to Use This Tool?
-
Enter the value of the data transfer rate in SCSI (LVD Ultra80)
-
Select SCSI (LVD Ultra80) as the source unit and IDE (PIO mode 1) as the target unit
-
Click convert to view the equivalent IDE (PIO mode 1) transfer rate
Key Features
-
Converts data transfer rates between SCSI (LVD Ultra80) and IDE (PIO mode 1)
-
Browser-based and easy to use with simple input and selection options
-
Provides conversions relevant for legacy and enterprise storage environments
Examples
-
2 SCSI (LVD Ultra80) corresponds to 30.7692307692 IDE (PIO mode 1)
-
0.5 SCSI (LVD Ultra80) converts to 7.6923076923 IDE (PIO mode 1)
Common Use Cases
-
Comparing data transfer speeds between high-performance SCSI drives and legacy PATA drives
-
Diagnosing compatibility and performance issues in mixed storage systems
-
Benchmarking data throughput on vintage or embedded computer systems
Tips & Best Practices
-
Use this tool to better understand throughput differences between legacy and modern data transfer standards
-
Apply conversions when developing or debugging firmware for legacy hardware
-
Consider real-world performance impacts beyond theoretical conversion values when planning system upgrades
Limitations
-
Conversion values represent theoretical throughput and do not include CPU overhead or protocol-specific delays
-
Performance differs since IDE (PIO mode 1) involves higher CPU usage and lower bus efficiency compared to SCSI (LVD Ultra80)
-
Real-world data transfer speeds may vary due to hardware and environmental factors
Frequently Asked Questions
-
What does SCSI (LVD Ultra80) refer to?
-
It is the Low Voltage Differential version of the Ultra2 SCSI interface that offers up to 80 MB/s on a 16-bit bus using 40 MHz synchronous transfers with enhanced cable length and noise immunity.
-
What is IDE (PIO mode 1)?
-
IDE (PIO mode 1) is a CPU-controlled data transfer mode for PATA devices providing low to moderate throughput compared to DMA modes, defined by legacy ATA/PATA standards.
-
Why convert between these two units?
-
Conversion assists in comparing data transfer speeds for performance analysis, compatibility checking, and integrating legacy and modern storage hardware.
Key Terminology
-
SCSI (LVD Ultra80)
-
A high-speed Low Voltage Differential SCSI interface offering up to 80 MB/s with improved noise immunity and cable lengths on a wide 16-bit bus.
-
IDE (PIO mode 1)
-
A Programmed Input/Output data transfer mode for PATA devices where the CPU controls each transfer cycle, providing lower throughput with higher CPU overhead.
-
Conversion Rate
-
The factor used to translate values from SCSI (LVD Ultra80) to IDE (PIO mode 1), specified as 1 SCSI (LVD Ultra80) equals approximately 15.38 IDE (PIO mode 1).
