What Is This Tool?
This converter allows you to translate data transfer rates from SCSI (Async), which is the asynchronous transfer mode of the SCSI protocol, into equivalent speeds of a 14.4k dial-up modem, enabling easier comparison and understanding of performance between these distinct data transfer technologies.
How to Use This Tool?
-
Enter the value in SCSI (Async) data transfer units you want to convert.
-
Select the target unit as modem (14.4k) from the available options.
-
Run the conversion to see the equivalent modem speed based on the provided formula.
Key Features
-
Converts asynchronous SCSI data rates to modem (14.4k) rates using a precise conversion factor.
-
Browser-based unit conversion for ease of use without installation.
-
Supports comparisons relevant to legacy and retro computing environments.
Examples
-
1 SCSI (Async) equals approximately 833.33 modem (14.4k) units.
-
0.5 SCSI (Async) converts to about 416.67 modem (14.4k) units.
Common Use Cases
-
Benchmarking throughput of legacy SCSI devices operating asynchronously.
-
Troubleshooting handshaking and compatibility issues on SCSI bus systems.
-
Comparing data transfer speeds for retrocomputing hardware and dial-up communication equipment.
-
Supporting telecommunications and network maintenance involving legacy asynchronous SCSI and modem technologies.
Tips & Best Practices
-
Verify device response times when interpreting SCSI (Async) throughput due to its variability.
-
Consider that modem (14.4k) speeds denote theoretical maximum rates and may differ in actual use.
-
Use this tool primarily for raw data rate comparisons without protocol overhead considerations.
Limitations
-
SCSI (Async) throughput depends greatly on hardware response and bus arbitration, causing fluctuating performance.
-
The 14.4k modem data rate represents an ideal maximum, with real speeds impacted by line conditions.
-
Conversion values exclude effects of error correction and communication protocol overhead.
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 instead of a shared clock.
-
What is a modem (14.4k)?
-
A 14.4k modem is a dial-up modem capable of transferring data at a maximum rate of 14.4 kilobits per second over analog telephone lines.
-
Why convert between SCSI (Async) and modem (14.4k)?
-
Converting helps compare and translate throughput rates of legacy SCSI devices into modem speeds, aiding understanding across different communication technologies.
Key Terminology
-
SCSI (Async)
-
The asynchronous data-transfer mode of the SCSI protocol using request/acknowledge handshakes, without a shared clock.
-
Modem (14.4k)
-
A dial-up modem with a maximum raw transfer speed of 14.4 kbps, operating over analog telephone lines.
-
Bus Arbitration
-
The process of managing access to the SCSI bus among multiple devices to prevent data conflicts.
