What Is This Tool?
This tool converts data transfer values from IDE (PIO mode 2) to SCSI (Async), aiding in the comparison and translation of legacy transfer speeds between older CPU-driven IDE interfaces and asynchronous SCSI devices.
How to Use This Tool?
-
Enter the data transfer value in IDE (PIO mode 2) units.
-
Select IDE (PIO mode 2) as the input unit and SCSI (Async) as the output unit.
-
Click the convert button to view the equivalent transfer rate in SCSI (Async).
Key Features
-
Supports conversion between IDE (PIO mode 2) and SCSI (Async) data transfer units.
-
Browser-based, easy to use for vintage PC maintenance and retrocomputing tasks.
-
Provides practical example conversions for clarity and reference.
Examples
-
2 IDE (PIO mode 2) equals 11.0666666666 SCSI (Async).
-
0.5 IDE (PIO mode 2) equals 2.76666666665 SCSI (Async).
Common Use Cases
-
Interpreting or configuring legacy BIOS/firmware drive timings on older IDE drives.
-
Benchmarking performance of vintage SCSI devices operating asynchronously.
-
Diagnosing compatibility or timing issues in retro or embedded systems using these legacy interfaces.
Tips & Best Practices
-
Use this converter when working with vintage PCs or archival hardware to understand relative transfer speeds.
-
Combine results with hardware diagnostics to accurately assess device performance.
-
Remember to verify device mode settings when troubleshooting legacy bus timing or compatibility.
Limitations
-
Conversions represent relative transfer timing and not absolute throughput rates.
-
Effective performance may vary due to device-specific implementations and bus arbitration delays.
-
Both units pertain to legacy technologies not used in modern computing systems.
Frequently Asked Questions
-
What does IDE (PIO mode 2) refer to?
-
IDE (PIO mode 2) is a legacy ATA/IDE interface timing standard for CPU-driven, programmed input/output data transfers commonly used in older hard and optical drives.
-
How is SCSI (Async) characterized?
-
SCSI (Async) means asynchronous data transfer using request/acknowledge handshakes without a shared clock, depending on device response and arbitration for throughput.
-
Why convert between IDE (PIO mode 2) and SCSI (Async)?
-
Converting helps compare legacy transfer speeds and troubleshoot performance or compatibility across different older storage technologies.
Key Terminology
-
IDE (PIO mode 2)
-
A legacy ATA/IDE interface timing mode for CPU-driven data transfers using programmed input/output cycles in older storage devices.
-
SCSI (Async)
-
An asynchronous data transfer mode in the SCSI protocol exchanging data via request/acknowledge handshakes without a shared clock.
-
Data transfer
-
The movement of data between a host system and a storage device, measured here using legacy interface timing standards.
