What Is This Tool?
This tool converts data transfer rates from the SCSI (Fast Wide) interface, used mainly in legacy disk subsystems, to modem (56k) dial-up modem speeds. It helps compare fast storage transfer rates against much slower dial-up connections, providing useful insights in legacy computing and network planning.
How to Use This Tool?
-
Enter the value in SCSI (Fast Wide) units that you wish to convert.
-
Select SCSI (Fast Wide) as the source unit and modem (56k) as the target unit.
-
Click convert to see the equivalent modem (56k) data transfer rate.
Key Features
-
Converts data transfer units between SCSI (Fast Wide) and modem (56k).
-
Browser-based and easy to use with straightforward input and output.
-
Helps understand performance differences between storage and dial-up communication speeds.
Examples
-
1 SCSI (Fast Wide) equals approximately 2857 modems (56k).
-
0.5 SCSI (Fast Wide) is about 1428.57 modems (56k).
Common Use Cases
-
Assessing speed differences between high-throughput storage interfaces and dial-up modems.
-
Planning data migration or fallback communication strategies involving legacy devices.
-
Analyzing performance gaps in telecommunications and legacy computing environments.
Tips & Best Practices
-
Consider hardware and line quality when interpreting conversion results.
-
Remember these units represent different transfer environments: local bus vs telephone lines.
-
Use this conversion as a comparative tool rather than an exact performance predictor.
Limitations
-
The 20 MB/s speed for SCSI (Fast Wide) may vary due to device negotiation and hardware design.
-
56k modem speeds often fall below the theoretical maximum because of line noise and quality.
-
Direct comparisons can be misleading since these units reflect different data transfer technologies.
Frequently Asked Questions
-
What is SCSI (Fast Wide)?
-
SCSI (Fast Wide) is a SCSI-2 interface mode with a 16-bit wide bus and 10 MHz signaling, offering a theoretical max throughput around 20 MB/s, mainly used for connecting storage devices in legacy systems.
-
What does a 56k modem represent?
-
A 56k modem is a dial-up modem that transmits digital data over telephone lines with a theoretical max downstream speed of around 56 kilobits per second.
-
Why convert between SCSI (Fast Wide) and modem (56k)?
-
Converting these units helps compare vastly different data transfer speeds, useful for understanding legacy system performance or planning fallbacks in data communication.
Key Terminology
-
SCSI (Fast Wide)
-
A SCSI-2 interface mode combining 10 MHz Fast timing with a 16-bit wide data bus to increase transfer rates up to 20 MB/s in legacy storage systems.
-
56k modem
-
A dial-up modem standard using ITU V.90 or V.92 that modulates digital data over telephone lines with a max downstream rate of about 56 kbps.
-
Data Transfer Rate
-
The speed at which data is transferred, measured differently depending on the technology and environment.
