What Is This Tool?
This converter helps translate data transfer rates from the high-speed SCSI (LVD Ultra160) parallel interface to the much slower 14.4k modem standard, allowing users to compare legacy storage bus speeds with traditional dial-up modem rates.
How to Use This Tool?
-
Enter the data transfer speed value in SCSI (LVD Ultra160) unit.
-
Select the target unit as modem (14.4k).
-
Click the convert button to get the equivalent transfer rate.
-
Review the result to compare the performance difference.
-
Use the conversion to aid in legacy system or bandwidth planning.
Key Features
-
Converts data transfer speeds between SCSI (LVD Ultra160) and modem (14.4k).
-
Displays maximum theoretical transfer rate equivalence.
-
Helps in legacy system assessment and bandwidth comparison.
-
Browser-based and easy to operate.
-
Includes practical examples for quick understanding.
Examples
-
Converting 2 SCSI (LVD Ultra160) results in 177777.78 modem (14.4k).
-
Converting 0.5 SCSI (LVD Ultra160) results in 44444.44 modem (14.4k).
Common Use Cases
-
Specifying maximum data transfer for internal disk arrays and RAID controllers in older servers.
-
Comparing throughput of legacy tape drives and backup interfaces using parallel SCSI.
-
Understanding legacy storage bus bandwidth during system migrations.
-
Reviewing early dial-up modem capabilities for remote access and telemetry.
-
Planning telecommunications history studies or performance benchmarks.
Tips & Best Practices
-
Use the converter to highlight the speed gap between storage and modem technologies.
-
Consider protocol overhead and real-world factors as actual speeds may vary.
-
Use this tool as a benchmarking aid in legacy system maintenance.
-
Apply the conversion primarily for theoretical and planning purposes.
Limitations
-
Conversion reflects only maximum theoretical data transfer rates.
-
Real transfer speeds may differ due to protocol overhead and line conditions.
-
The units represent fundamentally different technologies, so practical interchangeability is limited.
Frequently Asked Questions
-
What does SCSI (LVD Ultra160) measure?
-
It measures the maximum sustained data transfer throughput between a host adapter and SCSI storage devices using a parallel interface with Low Voltage Differential signalling.
-
What is a 14.4k modem used for?
-
A 14.4k modem is used for dial-up internet access, remote terminal sessions, file transfers over telephone lines, and low-bandwidth communications such as telemetry and legacy fax data.
-
Can I directly replace SCSI with modem speeds in my system?
-
No, because these units relate to different technologies; SCSI is for internal storage interfaces while modems operate over analog phone lines with much lower speeds.
Key Terminology
-
SCSI (LVD Ultra160)
-
A parallel SCSI interface standard using Low Voltage Differential signalling with up to 160 MB/s bandwidth for storage device communication.
-
Modem (14.4k)
-
An analog dial-up modem capable of a maximum 14.4 kbps raw data transfer rate, used for communication over telephone lines.
-
Data Transfer Rate
-
The speed at which data is transmitted between devices, often measured in bits or bytes per second.
