What Is This Tool?
This converter helps you translate data transfer rates between IDE (UDMA mode 1), a legacy Parallel ATA transfer mode, and SCSI (LVD Ultra160), a parallel SCSI interface standard. It is useful for comparing performance and evaluating compatibility in older computing environments.
How to Use This Tool?
-
Enter the numerical value representing your IDE (UDMA mode 1) transfer rate.
-
Select IDE (UDMA mode 1) as the unit to convert from.
-
Choose SCSI (LVD Ultra160) as the target unit.
-
Click the convert button to obtain the equivalent data transfer rate.
-
Review the conversion results to compare or plan system upgrades.
Key Features
-
Supports conversion between IDE (UDMA mode 1) and SCSI (LVD Ultra160) data transfer units.
-
Based on theoretical maximum transfer rates defined by relevant standards.
-
Useful for analyzing legacy PC storage and server RAID controller bandwidth.
-
Browser-based and easy to use without any installation.
-
Provides quick and accurate conversion for performance comparison.
Examples
-
1 IDE (UDMA mode 1) equals 0.15625 SCSI (LVD Ultra160).
-
4 IDE (UDMA mode 1) equals 0.625 SCSI (LVD Ultra160).
Common Use Cases
-
Specifying or diagnosing BIOS and drive transfer settings on vintage PCs using UDMA modes.
-
Benchmarking throughput performance of older IDE hard disks compared to modern SCSI devices.
-
Planning data migration or system upgrades involving legacy PATA and SCSI storage interfaces.
-
Assessing server storage bandwidth and RAID controller configurations in legacy systems.
Tips & Best Practices
-
Ensure accurate input values for precise conversion results.
-
Use this tool to estimate comparative transfer rates rather than exact current speeds.
-
Consider hardware conditions and system setup when interpreting conversion results.
-
Apply conversions when troubleshooting compatibility or performance issues in vintage hardware.
-
Leverage this tool for planning migrations or comparing legacy storage bandwidth requirements.
Limitations
-
Conversion is based on theoretical maximum transfer rates, not actual throughput.
-
Actual speeds depend on factors like hardware quality, cabling, and system configuration.
-
Legacy PATA devices operate at much lower speeds than SCSI LVD Ultra160, limiting direct performance equivalence.
-
This converter does not account for error rates or real-world operational conditions.
Frequently Asked Questions
-
What does IDE (UDMA mode 1) mean?
-
IDE (UDMA mode 1) is an Ultra DMA transfer mode in the Parallel ATA interface providing a theoretical maximum transfer rate of about 25 MB/s, used mainly in older PATA devices.
-
What is SCSI (LVD Ultra160)?
-
SCSI (LVD Ultra160) refers to a parallel SCSI interface standard using Low Voltage Differential signaling with a maximum channel bandwidth of up to 160 MB/s.
-
Why convert data transfer rates between these two units?
-
Converting helps compare performance and compatibility between older PATA devices and faster SCSI storage systems, aiding in system diagnostics and upgrade planning.
