What Is This Tool?
This unit converter transforms data transfer rates between SCSI (Fast Wide) and IDE (PIO mode 2), allowing users to compare and configure legacy storage device performance accurately.
How to Use This Tool?
-
Enter the value in SCSI (Fast Wide) units that you want to convert
-
Select SCSI (Fast Wide) as the source unit and IDE (PIO mode 2) as the target unit
-
Submit the input to receive the equivalent IDE (PIO mode 2) value based on the conversion ratio
-
Use the results to assist with configuring or diagnosing legacy hardware systems
Key Features
-
Supports data transfer unit conversions between SCSI (Fast Wide) and IDE (PIO mode 2)
-
Uses a precise conversion factor derived from legacy hardware standards
-
Ideal for IT hardware maintenance and retro computing scenarios
-
Browser-based and easy to use without requiring installation
Examples
-
1 SCSI (Fast Wide) equals approximately 2.41 IDE (PIO mode 2)
-
5 SCSI (Fast Wide) converts to about 12.05 IDE (PIO mode 2)
Common Use Cases
-
Comparing legacy SCSI device data rates to equivalent IDE timing modes
-
Configuring BIOS or firmware drive settings for older IDE drives
-
Diagnosing performance considerations in vintage computers
-
Relating drive transfer modes in device driver utility reports
Tips & Best Practices
-
Verify device negotiation details for accurate throughput understanding
-
Consider hardware differences such as cable length when interpreting conversions
-
Use conversions primarily for legacy hardware contexts
-
Cross-check results with device specifications and driver reports
Limitations
-
Actual throughput can vary due to hardware implementation differences and device negotiation
-
PIO mode 2 is a CPU-driven transfer mode, typically slower than DMA-based modes
-
The conversion is mainly relevant for legacy computing and does not reflect modern storage technologies
Frequently Asked Questions
-
What does SCSI (Fast Wide) mean?
-
SCSI (Fast Wide) is a SCSI-2 interface mode combining 10 MHz fast timing with a 16-bit data bus, aiming for up to 20 MB/s throughput in legacy systems.
-
What is IDE (PIO mode 2)?
-
IDE (PIO mode 2) is an ATA/IDE interface timing mode used for programmed input/output data transfers, common in older IDE drives.
-
Why convert between SCSI (Fast Wide) and IDE (PIO mode 2)?
-
Converting between these units helps configure or diagnose legacy systems where SCSI and IDE devices coexist, providing a common frame of reference.
