What Is This Tool?
This converter transforms data transfer values from IDE (PIO mode 3), a CPU-driven Parallel ATA mode, to SCSI (Sync), a synchronous transfer mode in the SCSI protocol. It helps users compare and adapt storage throughput between these legacy and higher-performance technologies.
How to Use This Tool?
-
Enter the data transfer value in IDE (PIO mode 3) units
-
Select IDE (PIO mode 3) as the source unit and SCSI (Sync) as the target unit
-
Click convert to see the equivalent value in SCSI (Sync)
-
Use the conversion results to analyze or optimize storage performance
Key Features
-
Converts data transfer units from IDE (PIO mode 3) to SCSI (Sync)
-
Based on standardized conversion rates reflecting theoretical maximum throughput
-
Supports comparisons between legacy and modern storage transfer modes
-
Browser-based and easy to use with no installation required
Examples
-
1 IDE (PIO mode 3) equals 2.22 SCSI (Sync)
-
5 IDE (PIO mode 3) converts to 11.1 SCSI (Sync)
Common Use Cases
-
Evaluating legacy desktop or laptop hard drive speeds in BIOS mode
-
Configuring RAID controllers and storage arrays for deterministic latency
-
Benchmarking and performance testing in retrocomputing and industrial systems
-
Negotiating transfer speeds with legacy SCSI devices in server environments
Tips & Best Practices
-
Verify the mode of your devices before converting to ensure accurate context
-
Use the converter to compare theoretical throughput for system optimization
-
Consider environmental and hardware overheads as they affect actual transfer rates
-
Combine conversion results with practical testing for reliable performance insights
Limitations
-
Conversion reflects theoretical maximum throughput, not actual performance
-
IDE (PIO mode 3) efficiency is limited by CPU-driven data transfers without DMA
-
Real-world rates may differ due to hardware and system overhead factors
Frequently Asked Questions
-
What does IDE (PIO mode 3) mean in data transfer?
-
IDE (PIO mode 3) is a CPU-driven programmed I/O transfer mode for Parallel ATA devices with a maximum theoretical throughput around 11.1 MB/s.
-
What is SCSI (Sync) transfer mode?
-
SCSI (Sync) is a synchronous data transfer mode in the SCSI protocol that uses a negotiated clock between devices to enable higher throughput and predictable timing.
-
Why convert IDE (PIO mode 3) to SCSI (Sync)?
-
Converting helps compare performance between legacy IDE devices and modern SCSI storage systems, optimizing compatibility and throughput in mixed hardware setups.
Key Terminology
-
IDE (PIO mode 3)
-
A CPU-controlled programmed I/O transfer mode for Parallel ATA devices with a theoretical max throughput of about 11.1 MB/s.
-
SCSI (Sync)
-
A synchronous transfer mode in the SCSI protocol where data is transferred in lockstep with a negotiated clock, allowing higher throughput.
-
Data Transfer Rate
-
The amount of data moved from one place to another in a given amount of time, often measured in bytes per second.
