What Is This Tool?
This unit converter enables users to translate data transfer rates from the asynchronous SCSI mode (SCSI Async) to the faster, wider parallel mode known as SCSI (Fast Ultra Wide). It aids in comparing and understanding transfer capabilities across different SCSI interface types used in legacy computing environments.
How to Use This Tool?
-
Enter the value in SCSI (Async) data transfer units you wish to convert.
-
Select SCSI (Async) as the source unit and SCSI (Fast Ultra Wide) as the target unit.
-
Click the convert button to obtain the equivalent transfer rate in SCSI (Fast Ultra Wide).
Key Features
-
Converts SCSI (Async) data transfer values to SCSI (Fast Ultra Wide) equivalents.
-
Supports data transfer measurement relevant to legacy SCSI storage devices and controllers.
-
Browser-based and easy to use for IT professionals and retrocomputing enthusiasts.
Examples
-
10 SCSI (Async) converts to 0.375 SCSI (Fast Ultra Wide).
-
100 SCSI (Async) converts to 3.75 SCSI (Fast Ultra Wide).
Common Use Cases
-
Benchmarking or reporting throughput of legacy SCSI devices operating asynchronously.
-
Troubleshooting timing and handshake issues on SCSI buses between initiator and target devices.
-
Configuring or testing embedded systems or retrocomputing setups with asynchronous SCSI.
-
Comparing performance for system upgrades between different SCSI transfer modes.
-
Supporting legacy enterprise backups or connecting older RAID controllers using parallel SCSI.
Tips & Best Practices
-
Use the converter to assess relative data transfer performance rather than absolute throughput.
-
Consider device response times and bus arbitration which affect asynchronous transfer behavior.
-
Apply results carefully in legacy system environments due to variability in hardware and cabling conditions.
Limitations
-
Conversion indicates relative bus signaling and transfer capability, not standardized unit precision.
-
Performance results depend heavily on device-specific factors like response times and physical setup.
-
Legacy interfaces may have age and configuration variability affecting practical throughput.
Frequently Asked Questions
-
What does SCSI (Async) mean?
-
SCSI (Async) refers to the asynchronous data transfer mode of the SCSI protocol where communication uses request/acknowledge handshakes instead of a shared clock, affecting effective throughput based on device response.
-
Why convert SCSI (Async) to SCSI (Fast Ultra Wide)?
-
Users convert between these units to compare throughput performance across legacy SCSI devices and interfaces, especially for benchmarking, upgrading systems, or compatibility analysis.
-
Is this conversion exact?
-
No, the conversion reflects relative transfer capabilities and bus signaling differences rather than exact standardized units, with actual performance varying by hardware conditions.
Key Terminology
-
SCSI (Async)
-
An asynchronous SCSI transfer mode using request/acknowledge handshakes instead of a shared clock, with throughput depending on response times and bus arbitration.
-
SCSI (Fast Ultra Wide)
-
A legacy parallel SCSI mode featuring a wider data bus (typically 16 bits) and faster signalling to enable higher sustained data transfer rates.
-
Data Transfer
-
The movement of digital information between devices or components, commonly measured in terms of throughput or speed.
