What Is This Tool?
This converter transforms data transfer measurements from SCSI (Fast Ultra) units to IDE (DMA mode 2) units, enabling comparisons and translations of transfer rates between these two legacy parallel interface modes.
How to Use This Tool?
-
Enter the value in SCSI (Fast Ultra) data transfer units
-
Select SCSI (Fast Ultra) as the input unit and IDE (DMA mode 2) as the output unit
-
Click the convert button to view the equivalent IDE (DMA mode 2) transfer rate
Key Features
-
Browser-based and user-friendly interface for quick conversion
-
Supports conversion between legacy data transfer modes used in older hardware
-
Displays conversions using the specific rate of 1 SCSI (Fast Ultra) = 1.2048192771 IDE (DMA mode 2)
-
Helps assess performance and compatibility across mixed legacy systems
Examples
-
1 SCSI (Fast Ultra) converts to approximately 1.2048 IDE (DMA mode 2)
-
5 SCSI (Fast Ultra) converts to about 6.0241 IDE (DMA mode 2)
Common Use Cases
-
Comparing data transfer rates between SCSI and IDE devices on legacy hardware
-
Performance tuning and compatibility assessment on older storage systems
-
Benchmarking or diagnosing data transfer performance in legacy PATA/IDE and SCSI setups
Tips & Best Practices
-
Confirm the specific transfer modes of your devices before converting
-
Use the converter to assist in firmware or BIOS configuration decisions
-
Apply conversions when troubleshooting legacy storage interface speed issues
Limitations
-
Conversion applies only to legacy parallel interface standards, excluding modern serial protocols like SATA or NVMe
-
Raw conversion rates do not reflect factors such as device firmware, system architecture, or workload variations
Frequently Asked Questions
-
What does SCSI (Fast Ultra) refer to?
-
SCSI (Fast Ultra) refers to parallel SCSI signalling modes combining the Fast and Ultra extensions to boost device-to-host throughput and reduce latency while maintaining compatibility with the SCSI command set.
-
What is IDE (DMA mode 2)?
-
IDE (DMA mode 2) is a Parallel ATA data-transfer mode allowing an IDE device to move data directly to or from system memory with less CPU involvement, offering higher throughput than PIO modes.
-
Why convert between these units?
-
Converting helps compare and translate data transfer rates between legacy storage interfaces to support performance tuning, compatibility assessment, and benchmarking in systems using mixed hardware.
Key Terminology
-
SCSI (Fast Ultra)
-
A parallel SCSI signalling mode combining Fast and Ultra extensions to increase throughput and reduce latency while supporting the SCSI command set.
-
IDE (DMA mode 2)
-
A Parallel ATA data-transfer mode enabling direct memory access with minimal CPU overhead, part of legacy IDE interface standards.
-
Data Transfer Rate
-
The speed at which data is moved from one device or interface to another, measured here between different legacy hardware transfer modes.
