What Is This Tool?
This converter facilitates comparing maximum theoretical data transfer rates between the IDE (UDMA mode 1) and SCSI (Ultra-3) interfaces, which are legacy standards used in different storage environments.
How to Use This Tool?
-
Enter the value in IDE (UDMA mode 1) units you want to convert.
-
Select IDE (UDMA mode 1) as the source unit and SCSI (Ultra-3) as the target unit.
-
Click the convert button to get the equivalent value in SCSI (Ultra-3).
-
Review the results to understand the theoretical maximum transfer rate comparison.

Examples
-
1 IDE (UDMA mode 1) equals 0.15625 SCSI (Ultra-3).
-
4 IDE (UDMA mode 1) equals 0.625 SCSI (Ultra-3).
Common Use Cases
-
Specifying or diagnosing transfer settings on vintage PCs and PATA drives.
-
Benchmarking maximum throughput for older IDE hard disks or optical drives.
-
Connecting enterprise hard drives and RAID controllers in legacy servers.
-
Configuring tape drives and backup libraries in data-center systems.
-
Designing or diagnosing storage subsystems involving both IDE and SCSI interfaces.
Tips & Best Practices
-
Use this converter to compare theoretical speeds when managing legacy storage devices.
-
Verify settings when troubleshooting data errors due to transfer mode incompatibilities.
-
Keep in mind the converter focuses on raw transfer rates, not real-world throughput.
-
Apply conversions primarily in contexts where both IDE and SCSI standards coexist.
Limitations
-
Conversion is based only on theoretical maximum raw transfer rates, excluding overhead.
-
Does not account for device-specific performance or bus efficiency differences.
-
Limited to legacy hardware scenarios involving IDE (UDMA mode 1) and SCSI (Ultra-3).
Frequently Asked Questions
-
What does IDE (UDMA mode 1) represent?
-
IDE (UDMA mode 1) is a transfer mode in the Parallel ATA interface providing around 25 MB/s maximum raw transfer rate, mainly for older PATA drives.
-
What is SCSI (Ultra-3)?
-
SCSI (Ultra-3) is a parallel SCSI interface standard that defines signaling and bus management for block-level data transfers in storage systems, used in enterprise storage and backup solutions.
-
Why convert between IDE (UDMA mode 1) and SCSI (Ultra-3)?
-
Conversion helps compare legacy PATA and SCSI interface speeds for diagnosing, benchmarking, or designing systems involving both device types.
Key Terminology
-
IDE (UDMA mode 1)
-
A legacy Ultra DMA transfer mode used with Parallel ATA interfaces providing about 25 MB/s theoretical maximum transfer rate.
-
SCSI (Ultra-3)
-
A generation of the parallel Small Computer System Interface standard for signaling and bus management in storage subsystems.
-
Transfer Rate
-
The speed at which data is transmitted from one device or interface to another.
