What Is This Tool?
This tool allows you to convert data transfer metrics from SCSI (Async), an asynchronous data transfer mode used in legacy SCSI devices, to USB, a widely used modern serial communication standard. It helps relate the performance of older SCSI devices to modern USB interfaces.
How to Use This Tool?
-
Enter the data transfer value in SCSI (Async) units
-
Select SCSI (Async) as the source unit and USB as the target unit
-
Click convert to see the equivalent value in USB units
Key Features
-
Supports conversion between SCSI (Async) and USB data transfer units
-
Provides definitions and use cases for both SCSI (Async) and USB
-
Simple conversion based on a 1 to 1 equivalence formula
-
Useful for benchmarking, troubleshooting, and retrocomputing scenarios
Examples
-
5 SCSI (Async) = 5 USB
-
10 SCSI (Async) = 10 USB
Common Use Cases
-
Benchmarking throughput of legacy SCSI devices operating asynchronously
-
Troubleshooting timing and handshake issues in SCSI bus communications
-
Testing embedded or retrocomputing systems using asynchronous SCSI
-
Translating data transfer rates for interoperability between legacy SCSI and modern USB devices
Tips & Best Practices
-
Consider device response times when interpreting SCSI (Async) data transfer rates
-
Account for USB generation and device capabilities when comparing speeds
-
Use this conversion as a formal equivalence rather than an exact performance match
-
Apply the tool in contexts involving legacy hardware benchmarking and embedded system development
Limitations
-
The conversion reflects a formal equivalence, not true throughput equality
-
SCSI (Async) performance depends on device and bus timing factors
-
USB speeds vary significantly based on generation and device specifications
-
Real-world transfer rates may differ despite numeric equivalence
Frequently Asked Questions
-
What does SCSI (Async) mean?
-
SCSI (Async) is the asynchronous data-transfer mode of the SCSI protocol where data is exchanged using request/acknowledge handshakes instead of a shared clock.
-
What is USB used for?
-
USB is an industry-standard interface for data communication and power delivery between host devices like computers and various peripherals.
-
Is the conversion rate between SCSI (Async) and USB always 1:1?
-
Yes, this tool uses a formal equivalence of 1 SCSI (Async) equals 1 USB to translate data transfer values, but actual throughput may differ in practice.
Key Terminology
-
SCSI (Async)
-
An asynchronous data-transfer mode in SCSI devices that relies on request/acknowledge handshakes instead of a shared clock.
-
USB
-
Universal Serial Bus, a standard interface and protocol for data communication and power delivery between hosts and peripherals.
-
Data Transfer Rate
-
The speed at which data is transmitted from one device to another, often measured in megabits or gigabits per second.
