What Is This Tool?
This converter transforms data transfer values from SCSI (Async), an asynchronous transfer mode for SCSI devices, to IDE (PIO mode 2), a legacy programmed I/O transfer mode used by older IDE storage devices.
How to Use This Tool?
-
Enter the data transfer value measured in SCSI (Async).
-
Select SCSI (Async) as the source unit and IDE (PIO mode 2) as the target unit.
-
Apply the conversion to obtain the equivalent transfer rate in IDE (PIO mode 2).
Key Features
-
Converts data transfer rates from SCSI (Async) to IDE (PIO mode 2) using a defined conversion factor.
-
Supports evaluation and comparison of legacy storage interface performance metrics.
-
Helpful in retrocomputing, embedded systems, and vintage PC maintenance scenarios.
-
Provides conversion examples to aid understanding of the process.
Examples
-
5 SCSI (Async) converts to approximately 0.9036 IDE (PIO mode 2).
-
10 SCSI (Async) converts to approximately 1.8072 IDE (PIO mode 2).
Common Use Cases
-
Benchmarking throughput for asynchronous SCSI and programmed I/O IDE drives.
-
Troubleshooting device response times and compatibility between SCSI and IDE storage devices.
-
Configuring or testing embedded or retrocomputing systems with legacy storage hardware.
-
Analyzing performance reports or firmware settings involving these transfer modes.
Tips & Best Practices
-
Verify device compatibility when interpreting converted transfer rates.
-
Use the conversion for legacy device analysis and avoid applying it to modern storage technologies.
-
Consider device response times and system configurations when evaluating throughput changes.
-
Utilize conversion examples as a guide for accurate data transfer interpretation.
Limitations
-
Conversion results are approximate due to differing protocols and hardware timing characteristics.
-
Applicable only to legacy devices; modern storage technologies use different transfer methods.
-
Effective throughput depends on device-specific response times and operating conditions.
Frequently Asked Questions
-
What does SCSI (Async) mean?
-
SCSI (Async) refers to an asynchronous data transfer mode in the SCSI protocol where data is exchanged using request and acknowledge handshakes instead of a shared clock.
-
What is IDE (PIO mode 2)?
-
IDE (PIO mode 2) is a legacy ATA/IDE interface timing mode defining CPU-driven programmed input/output data transfers between a host and storage device.
-
Why convert between SCSI (Async) and IDE (PIO mode 2)?
-
Converting between these units helps compare and translate data transfer rates of legacy storage devices, aiding in benchmarking, troubleshooting, and configuring mixed hardware systems.
Key Terminology
