What Is This Tool?
This converter transforms data transfer measurements from the legacy IDE (PIO mode 2) timing specification to the more advanced SCSI (LVD Ultra80) interface standard, enabling users to compare performance between these two types of computer storage interfaces.
How to Use This Tool?
-
Enter the numerical value in IDE (PIO mode 2) units you want to convert
-
Select IDE (PIO mode 2) as the from unit and SCSI (LVD Ultra80) as the to unit
-
Click the convert button to see the equivalent value in SCSI (LVD Ultra80)
-
Review the provided examples and conversion formula for clarity
Key Features
-
Converts data transfer values between IDE (PIO mode 2) and SCSI (LVD Ultra80) units
-
Displays clear conversion formulas and examples
-
Useful for legacy PC troubleshooting and enterprise storage evaluation
-
Browser-based tool requiring no installation
-
Supports understanding of transfer modes and performance comparisons
Examples
-
Convert 5 IDE (PIO mode 2) units to SCSI (LVD Ultra80): resulting in 0.51875 SCSI (LVD Ultra80)
-
Convert 10 IDE (PIO mode 2) units to SCSI (LVD Ultra80): resulting in 1.0375 SCSI (LVD Ultra80)
Common Use Cases
-
Analyzing legacy BIOS or firmware drive timing settings for older IDE hard drives
-
Diagnosing performance issues in vintage PCs using PIO transfer modes
-
Comparing or upgrading storage performance between IDE and enterprise SCSI interfaces
-
Configuring server disk arrays and external RAID enclosures
-
Managing enterprise backup and SAN storage with legacy SCSI connectivity
Tips & Best Practices
-
Use this converter when troubleshooting or assessing compatibility in legacy computing systems
-
Consider both IDE and SCSI use cases to interpret results meaningfully
-
Refer to conversion examples and formula to verify calculations
-
Understand that the conversion gives theoretical transfer rate equivalents, not real-world speeds
-
Use this tool as a comparative guide rather than an absolute performance measure
Limitations
-
Conversion reflects theoretical or relative transfer rates without real-world overhead factors
-
Does not account for bus saturation, device-specific performance, or protocol efficiencies
-
Hardware architecture and communication differences limit direct practical equivalence
Frequently Asked Questions
-
What does IDE (PIO mode 2) refer to?
-
It is a legacy ATA/IDE timing mode that defines CPU-driven data transfer timing for older IDE storage devices.
-
What is the significance of SCSI (LVD Ultra80)?
-
SCSI (LVD Ultra80) represents an advanced transfer interface with improved bandwidth, noise immunity, and cable length over single-ended SCSI.
-
Can this converter be used to determine exact real-world transfer speeds?
-
No, it provides theoretical transfer rate equivalents and does not account for real hardware or protocol overheads.
Key Terminology
-
IDE (PIO mode 2)

SCSI (LVD Ultra80)
-
A Low Voltage Differential SCSI variant offering up to 80 MB/s on a 16-bit bus with 40 MHz synchronous transfers.
-
Data Transfer
-
The process of moving data between two storage or interface devices within a computer system.
