What Is This Tool?
This tool allows you to convert data transfer measurements from IDE (PIO mode 3) to SCSI (Fast) units, supporting legacy storage interface comparisons and system compatibility assessments.
How to Use This Tool?
-
Enter the data transfer value in IDE (PIO mode 3) units.
-
Select IDE (PIO mode 3) as the starting unit and SCSI (Fast) as the target unit.
-
Click the convert button to get the equivalent SCSI (Fast) value.
-
Review the output to compare transfer rates between the two legacy standards.
Key Features
-
Converts data transfer rates between IDE (PIO mode 3) and Fast SCSI units.
-
Based on theoretical maximum throughput for legacy storage technologies.
-
Supports comparisons of Parallel ATA and parallel SCSI interfaces.
-
Useful for retrocomputing and embedded system evaluations.
-
Browser-based and easy to use without installation.
Examples
-
1 IDE (PIO mode 3) equals approximately 1.11 SCSI (Fast).
-
5 IDE (PIO mode 3) converts to about 5.55 SCSI (Fast).
Common Use Cases
-
Comparing data transfer speeds between legacy Parallel ATA and parallel SCSI devices.
-
Testing compatibility and performance in systems featuring IDE and SCSI hardware.
-
Supporting legacy hardware maintenance and data recovery tasks.
-
Evaluating embedded or industrial systems with older storage interfaces.
Tips & Best Practices
-
Use this converter primarily for theoretical maximum transfer rate comparisons.
-
Understand that actual transfer rates may differ due to hardware and system factors.
-
Employ this tool for legacy system analysis rather than modern storage evaluations.
-
Verify conversions within the context of specific device configurations and use scenarios.
Limitations
-
Both IDE (PIO mode 3) and Fast SCSI are legacy technologies with fixed theoretical speeds.
-
This conversion reflects ideal throughput and does not consider error handling or protocol differences.
-
Not suitable for modern serial or high-speed data transfer interfaces.
-
Performance may vary in practice due to device conditions and system overhead.
Frequently Asked Questions
-
What does IDE (PIO mode 3) refer to?
-
IDE (PIO mode 3) is a CPU-driven programmed I/O transfer mode for Parallel ATA/IDE devices with a maximum throughput of about 11.1 MB/s.
-
What is Fast SCSI?
-
Fast SCSI is an enhanced parallel SCSI interface that roughly doubles the original SCSI throughput to about 10 MB/s for connecting storage devices on legacy systems.
-
Why convert between IDE (PIO mode 3) and SCSI (Fast)?
-
Users convert between these units to compare data transfer speeds and assess compatibility between legacy Parallel ATA and SCSI storage devices.
Key Terminology
-
IDE (PIO mode 3)
-
A programmed I/O transfer mode for Parallel ATA/IDE devices with CPU-driven data transfer and a theoretical max throughput around 11.1 MB/s.
-
Fast SCSI
-
A parallel SCSI bus enhancement that increases the synchronous data transfer rate, typically doubling classic 8-bit SCSI throughput to about 10 MB/s.
-
Data Transfer Rate
-
The speed at which data moves from one device to another, often measured in megabytes per second (MB/s) for storage interfaces.
