What Is This Tool?
This converter helps you transform data transfer rates expressed in IDE (UDMA-66) units into equivalent SCSI (Fast) values. It is designed to support users working with legacy storage technologies for performance comparison and system compatibility evaluation.
How to Use This Tool?
-
Enter the data transfer value in IDE (UDMA-66) units.
-
Select SCSI (Fast) as the target unit for conversion.
-
Click the convert button to see the equivalent SCSI (Fast) rate.
-
Use the results to assist in legacy device benchmarking or system planning.
Key Features
-
Transforms data transfer rates from IDE (UDMA-66) to SCSI (Fast) units.
-
Supports legacy Parallel ATA and SCSI storage device benchmarks.
-
Browser-based and straightforward to use without special software.
-
Helps compare maximum theoretical transfer capabilities of both standards.
Examples
-
1 IDE (UDMA-66) × 6.6 = 6.6 SCSI (Fast)
-
3 IDE (UDMA-66) × 6.6 = 19.8 SCSI (Fast)
Common Use Cases
-
Comparing maximum data transfer rates between legacy Parallel ATA and SCSI interfaces.
-
Planning upgrades or compatibility checks for older computer systems.
-
Performing device performance benchmarking in archival and industrial settings.
-
Supporting maintenance of legacy server and workstation storage setups.
Tips & Best Practices
-
Use this converter mainly for theoretical maximum burst or transfer rates.
-
Consider legacy system requirements when applying conversion results.
-
Remember that real-world throughput may vary due to overhead or hardware factors.
-
Verify compatibility with device BIOS or operating system transfer modes.
Limitations
-
Conversion reflects theoretical max speeds only and excludes practical overhead effects.
-
Applies only to legacy technologies mostly replaced by modern serial interfaces.
-
Does not consider cable quality or device-specific performance variations.
Frequently Asked Questions
-
What is IDE (UDMA-66)?
-
IDE (UDMA-66) is a Parallel ATA transfer mode that specifies a maximum theoretical raw data rate of 66.7 megabytes per second, used in legacy PATA storage devices.
-
What does SCSI (Fast) mean?
-
Fast SCSI is a legacy enhancement that improves upon the original SCSI transfer rates by doubling throughput to about 10 MB/s via faster timing on an 8-bit parallel bus.
-
Why convert between IDE (UDMA-66) and SCSI (Fast)?
-
Conversion helps compare and translate the maximum data transfer rates between these legacy storage interfaces for benchmarking, compatibility checks, and system upgrade planning.
Key Terminology
-
IDE (UDMA-66)
-
A Parallel ATA transfer mode with a theoretical max raw data rate of 66.7 MB/s used for legacy PATA devices.
-
SCSI (Fast)
-
A legacy parallel SCSI bus extension that doubles original 8-bit SCSI throughput by increasing transfer speed to around 10 MB/s.
-
Data Transfer Rate
-
The speed at which data moves between devices, measured here in megabytes per second (MB/s).
