What Is This Tool?
This converter allows you to translate data transfer speeds between SCSI (LVD Ultra160), a parallel SCSI interface standard, and IDE (UDMA mode 4), a Parallel ATA transfer mode. It helps compare and evaluate bandwidth capabilities between these legacy storage technologies.
How to Use This Tool?
-
Enter the data transfer rate value in SCSI (LVD Ultra160) units
-
Select the target unit IDE (UDMA mode 4) for conversion
-
Initiate the conversion to obtain the equivalent IDE (UDMA mode 4) value
-
Use the results to compare bandwidth or assess hardware compatibility
Key Features
-
Converts maximum theoretical data transfer rates from SCSI (LVD Ultra160) to IDE (UDMA mode 4)
-
Supports legacy storage bandwidth comparisons and compatibility planning
-
Provides conversion based on known maximum throughput values
-
Easy to use with a clear formula and example conversions
-
Helps assess storage performance during hardware migration or maintenance
Examples
-
1 SCSI (LVD Ultra160) converts to approximately 2.42 IDE (UDMA mode 4)
-
0.5 SCSI (LVD Ultra160) converts to about 1.21 IDE (UDMA mode 4)
Common Use Cases
-
Specifying maximum data-transfer rates in legacy server storage arrays and RAID controllers
-
Benchmarking performance of tape drives and backup systems using parallel SCSI interfaces
-
Comparing throughput for storage migration or system compatibility assessments
-
Connecting and configuring older PATA/IDE drives and optical devices
-
Troubleshooting DMA modes and maintaining legacy hardware
Tips & Best Practices
-
Use the converter to facilitate hardware planning during migration from SCSI to IDE systems
-
Consider the maximum theoretical throughput values as a guideline rather than exact speeds
-
Apply results primarily for benchmarking and compatibility evaluation in legacy environments
-
Be aware of the cable and hardware requirements for IDE (UDMA mode 4), such as the 80-conductor cable
-
Regularly verify device firmware or BIOS settings when configuring IDE modes
Limitations
-
Conversion is based on maximum theoretical transfer rates and does not include real-world overhead or inefficiencies
-
Device-specific performance may vary and is not reflected in the conversion
-
Both units refer to older technologies with limited use as modern interfaces provide faster throughput
-
The tool does not account for protocol differences or detailed hardware configurations

Key Terminology
-
SCSI (LVD Ultra160)
-
A parallel SCSI standard that uses Low Voltage Differential signaling to deliver a maximum sustained data transfer rate up to 160 MB/s in storage systems.
-
IDE (UDMA mode 4)
-
A Parallel ATA transfer mode known as Ultra DMA/66 that enables data transfer speeds near 66.7 MB/s using an 80-conductor IDE cable.
-
Data Transfer Rate
-
The speed at which data is transmitted from one device to another, typically measured in megabytes per second (MB/s).
