What Is This Tool?
This converter translates data transfer units from SCSI (Async), the asynchronous mode of the Small Computer System Interface, to IDE (PIO mode 0), a CPU-driven ATA/IDE timing mode. It facilitates benchmarking, compatibility checks, and troubleshooting for vintage and legacy storage devices.
How to Use This Tool?
-
Enter the data transfer value in SCSI (Async) units
-
Select the target unit as IDE (PIO mode 0)
-
Click the convert button to see the equivalent transfer rate
-
Review conversion results to compare device performance or assist troubleshooting
Key Features
-
Converts data transfer rates between SCSI (Async) and IDE (PIO mode 0)
-
Supports benchmarking and performance comparison of legacy storage devices
-
Helps troubleshoot timing and compatibility issues in vintage computing systems
-
Browser-based and easy to use without software installation
Examples
-
2 SCSI (Async) converts to 0.9091 IDE (PIO mode 0)
-
5 SCSI (Async) converts to 2.2727 IDE (PIO mode 0)
Common Use Cases
-
Benchmarking asynchronous SCSI devices against old IDE PIO mode 0 drives
-
Testing and configuring retro or embedded systems using legacy storage protocols
-
Diagnosing timing or compatibility issues between SCSI and IDE storage hardware
-
Restoring vintage computers and recovering data from old storage devices
Tips & Best Practices
-
Use this tool to gain approximate throughput comparisons, not exact performance metrics
-
Consider device-specific factors when interpreting conversion results
-
Apply conversions mainly for legacy or embedded system troubleshooting and benchmarking
-
Understand that IDE (PIO mode 0) speeds reflect CPU-driven transfers with inherent limitations
Limitations
-
Conversion provides relative throughput approximations, not precise speed equivalences
-
SCSI (Async) transfer speeds vary with device response and bus arbitration
-
IDE (PIO mode 0) inherently limits throughput due to CPU-driven data transfers
-
Real-world performance may differ due to device and system-specific conditions
Frequently Asked Questions
-
What does SCSI (Async) mean?
-
SCSI (Async) refers to the asynchronous data-transfer mode of the SCSI protocol, using request/acknowledge handshakes without a shared clock, so transfer speed relies on device response times and arbitration.
-
What is IDE (PIO mode 0)?
-
IDE (PIO mode 0) is the slowest CPU-driven ATA/IDE data transfer mode, where the CPU manages reading and writing to device registers without DMA, typically supporting very old drives.
-
Why convert between SCSI (Async) and IDE (PIO mode 0)?
-
Conversions help compare and translate data transfer performance for legacy devices, aiding benchmarking, troubleshooting, and system compatibility between different vintage storage interfaces.
Key Terminology
-
SCSI (Async)
-
An asynchronous SCSI data transfer mode using request/acknowledge handshakes without a shared clock signal.
-
IDE (PIO mode 0)
-
A slow ATA/IDE data transfer timing mode driven by the CPU without DMA support.
-
Data Transfer Rate Conversion
-
The process of translating data throughput values from one unit or protocol to another for performance comparison.
